-
- TODO, in rough priority order:
- * dev->tx_timeout
- * LinkChg interrupt
- * ETHTOOL_[GS]SET
- * Support forcing media type with a module parameter,
- like dl2k.c/sundance.c
- * Implement PCI suspend/resume
- * Constants (module parms?) for Rx work limit
- * support 64-bit PCI DMA
- * Complete reset on PciErr
- * Consider Rx interrupt mitigation using TimerIntr
- * Implement 8139C+ statistics dump; maybe not...
- h/w stats can be reset only by software reset
- * Rx checksumming
- * Tx checksumming
- * ETHTOOL_GREGS, ETHTOOL_[GS]WOL,
- ETHTOOL_[GS]MSGLVL, ETHTOOL_NWAY_RST
- * Jumbo frames / dev->change_mtu
- * Investigate using skb->priority with h/w VLAN priority
- * Investigate using High Priority Tx Queue with skb->priority
- * Adjust Rx FIFO threshold and Max Rx DMA burst on Rx FIFO error
- * Adjust Tx FIFO threshold and Max Tx DMA burst on Tx FIFO error

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
-single-chip fast Ethernet controller for PCI, as used on the Intel
-EtherExpress Pro 100 adapter.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line. While it's
-possible to share PCI interrupt lines, it negatively impacts performance and
-only recent kernels support it.
-
-III. Driver operation
-
-IIIA. General
-The Speedo3 is very similar to other Intel network chips, that is to say
-"apparently designed on a different planet". This chips retains the complex
-Rx and Tx descriptors and multiple buffers pointers as previous chips, but
-also has simplified Tx and Rx buffer modes. This driver uses the "flexible"
-Tx mode, but in a simplified lower-overhead manner: it associates only a
-single buffer descriptor with each frame descriptor.
-
-Despite the extra space overhead in each receive skbuff, the driver must use
-the simplified Rx buffer mode to assure that only a single data buffer is
-associated with each RxFD. The driver implements this by reserving space
-for the Rx descriptor at the head of each Rx skbuff.
-
-The Speedo-3 has receive and command unit base addresses that are added to
-almost all descriptor pointers. The driver sets these to zero, so that all
-pointer fields are absolute addresses.
-
-The System Control Block (SCB) of some previous Intel chips exists on the
-chip in both PCI I/O and memory space. This driver uses the I/O space
-registers, but might switch to memory mapped mode to better support non-x86
-processors.
-
-IIIB. Transmit structure
-
-The driver must use the complex Tx command+descriptor mode in order to
-have a indirect pointer to the skbuff data section. Each Tx command block
-(TxCB) is associated with two immediately appended Tx Buffer Descriptor
-(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the
-speedo_private data structure for each adapter instance.
-
-The newer i82558 explicitly supports this structure, and can read the two
-TxBDs in the same PCI burst as the TxCB.
-
-This ring structure is used for all normal transmit packets, but the
-transmit packet descriptors aren't long enough for most non-Tx commands such
-as CmdConfigure. This is complicated by the possibility that the chip has
-already loaded the link address in the previous descriptor. So for these
-commands we convert the next free descriptor on the ring to a NoOp, and point
-that descriptor's link to the complex command.
-
-An additional complexity of these non-transmit commands are that they may be
-added asynchronous to the normal transmit queue, so we disable interrupts
-whenever the Tx descriptor ring is manipulated.
-
-A notable aspect of these special configure commands is that they do
-work with the normal Tx ring entry scavenge method. The Tx ring scavenge
-is done at interrupt time using the 'dirty_tx' index, and checking for the
-command-complete bit. While the setup frames may have the NoOp command on the
-Tx ring marked as complete, but not have completed the setup command, this
-is not a problem. The tx_ring entry can be still safely reused, as the
-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.
-
-Commands may have bits set e.g. CmdSuspend in the command word to either
-suspend or stop the transmit/command unit. This driver always flags the last
-command with CmdSuspend, erases the CmdSuspend in the previous command, and
-then issues a CU_RESUME.
-Note: Watch out for the potential race condition here: imagine
- erasing the previous suspend
- the chip processes the previous command
- the chip processes the final command, and suspends
- doing the CU_RESUME
- the chip processes the next-yet-valid post-final-command.
-So blindly sending a CU_RESUME is only safe if we do it immediately after
-after erasing the previous CmdSuspend, without the possibility of an
-intervening delay. Thus the resume command is always within the
-interrupts-disabled region. This is a timing dependence, but handling this
-condition in a timing-independent way would considerably complicate the code.
-
-Note: In previous generation Intel chips, restarting the command unit was a
-notoriously slow process. This is presumably no longer true.
-
-IIIC. Receive structure
-
-Because of the bus-master support on the Speedo3 this driver uses the new
-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
-This scheme allocates full-sized skbuffs as receive buffers. The value
-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
-trade-off the memory wasted by passing the full-sized skbuff to the queue
-layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-For small frames the copying cost is negligible (esp. considering that we
-are pre-loading the cache with immediately useful header information), so we
-allocate a new, minimally-sized skbuff. For large frames the copying cost
-is non-trivial, and the larger copy might flush the cache of useful data, so
-we pass up the skbuff the packet was received into.
-
-IV. Notes
-
-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
-that stated that I could disclose the information. But I still resent
-having to sign an Intel NDA when I'm helping Intel sell their own product!

- * Theory of Operation
- *
- * This driver uses the same software structure as the normal lance
- * driver. So look for a verbose description in lance.c. The differences
- * to the normal lance driver is the use of the 32bit mode of PCnet32
- * and PCnetPCI chips. Because these chips are 32bit chips, there is no
- * 16MB limitation and we don't need bounce buffers.

-/*
- * History:
- * v0.01: Initial version
- * only tested on Alpha Noname Board
- * v0.02: changed IRQ handling for new interrupt scheme (dev_id)
- * tested on a ASUS SP3G
- * v0.10: fixed an odd problem with the 79C974 in a Compaq Deskpro XL
- * looks like the 974 doesn't like stopping and restarting in a
- * short period of time; now we do a reinit of the lance; the
- * bug was triggered by doing ifconfig eth0 <ip> broadcast <addr>
- * and hangs the machine (thanks to Klaus Liedl for debugging)
- * v0.12: by suggestion from Donald Becker: Renamed driver to pcnet32,
- * made it standalone (no need for lance.c)
- * v0.13: added additional PCI detecting for special PCI devices (Compaq)
- * v0.14: stripped down additional PCI probe (thanks to David C Niemi
- * and sveneric@xs4all.nl for testing this on their Compaq boxes)
- * v0.15: added 79C965 (VLB) probe
- * added interrupt sharing for PCI chips
- * v0.16: fixed set_multicast_list on Alpha machines
- * v0.17: removed hack from dev.c; now pcnet32 uses ethif_probe in Space.c
- * v0.19: changed setting of autoselect bit
- * v0.20: removed additional Compaq PCI probe; there is now a working one
- * in arch/i386/bios32.c
- * v0.21: added endian conversion for ppc, from work by cort@cs.nmt.edu
- * v0.22: added printing of status to ring dump
- * v0.23: changed enet_statistics to net_devive_stats
- * v0.90: added multicast filter
- * added module support
- * changed irq probe to new style
- * added PCnetFast chip id
- * added fix for receive stalls with Intel saturn chipsets
- * added in-place rx skbs like in the tulip driver
- * minor cleanups
- * v0.91: added PCnetFast+ chip id
- * back port to 2.0.x
- * v1.00: added some stuff from Donald Becker's 2.0.34 version
- * added support for byte counters in net_dev_stats
- * v1.01: do ring dumps, only when debugging the driver
- * increased the transmit timeout
- * v1.02: fixed memory leak in pcnet32_init_ring()
- * v1.10: workaround for stopped transmitter
- * added port selection for modules
- * detect special T1/E1 WAN card and setup port selection
- * v1.11: fixed wrong checking of Tx errors
- * v1.20: added check of return value kmalloc (cpeterso@cs.washington.edu)
- * added save original kmalloc addr for freeing (mcr@solidum.com)
- * added support for PCnetHome chip (joe@MIT.EDU)
- * rewritten PCI card detection
- * added dwio mode to get driver working on some PPC machines
- * v1.21: added mii selection and mii ioctl
- * v1.22: changed pci scanning code to make PPC people happy
- * fixed switching to 32bit mode in pcnet32_open() (thanks
- * to Michael Richard <mcr@solidum.com> for noticing this one)
- * added sub vendor/device id matching (thanks again to
- * Michael Richard <mcr@solidum.com>)
- * added chip id for 79c973/975 (thanks to Zach Brown <zab@zabbo.net>)
- * v1.23 fixed small bug, when manual selecting MII speed/duplex
- * v1.24 Applied Thomas' patch to use TxStartPoint and thus decrease TxFIFO
- * underflows. Added tx_start_pt module parameter. Increased
- * TX_RING_SIZE from 16 to 32. Added #ifdef'd code to use DXSUFLO
- * for FAST[+] chipsets. <kaf@fc.hp.com>
- * v1.24ac Added SMP spinlocking - Alan Cox <alan@redhat.com>
- * v1.25kf Added No Interrupt on successful Tx for some Tx's <kaf@fc.hp.com>
- * v1.26 Converted to pci_alloc_consistent, Jamey Hicks / George France
- * <jamey@crl.dec.com>
- * v1.26p Fix oops on rmmod+insmod; plug i/o resource leak - Paul Gortmaker

-
- * tulip_core.c: Fix two comments
-
-2001-07-06 Stephen Degler <sdegler@degler.net>
-
- * media.c:
- The media selection process at the end of NWAY is busted
- because for the case of MII/SYM it needs to be:
-
- csr13 <- 0
- csr14 <- 0
- csr6 <- the value calculated is okay.
-
- In the other media cases csr14 is computed by
- t21142_csr14val[dev->if_port], which seems ok. The value of
- zero as opposed to 3FFFFF comes straight from appendix D of the
- 21143 data book, and it makes logical sense because you're
- bypassing all the SIA interface when you usa MII or SYM (see
- figure 1-1 in the data book if your're visually oriented)

-
- * tulip_core.c (tulip_mwi_config):
- Clamp values read from PCI cache line size register to
- values acceptable to tulip chip. Done for safety and
- -almost- certainly unneeded.
-
-2001-05-11 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c (tulip_init_one):
- Instead of unconditionally enabling autonegotiation, disable
- autonegotiation if not using the default port. Further,
- flip the nway bit immediately, and then update the
- speed/duplex in a separate MII transaction. We do this
- because some boards require that nway be disabled separately,
- before media selection is forced.
-
- TODO: Investigate if we can simply write the same value
- to BMCR twice, to avoid setting unnecessarily changing
- phy settings.
-
-2001-05-11 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip.h, tulip_core.c: If HAS_PCI_MWI is set for a
- given chip, adjust the csr0 values not according to
- provided values but according to system cache line size.
- Currently cache alignment is matched as closely to cache
- line size as possible. Currently programmable burst limit
- is set (ie. never unlimited), and always equal to cache
- alignment and system cache size. Currently MWI bit is set
- only if the MWI bit is present in the PCI command register.
-
-2001-05-11 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * media.c (tulip_select_media):
- For media types 1 and 3, only use the provided eeprom
- advertising value if it is non-zero.
- (tulip_check_duplex):
- Do not exit ASAP if full_duplex_lock is set. This
- ensures that the csr6 value is written if an update
- is needed.
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- Merge PNIC-II-specific stuff from Becker's tulip.c:
-
- * tulip.h, 21142.c (pnic2_lnk_change): new function
- * tulip_core.c (tulip_init_one): use it
-
- * tulip_core.c (tulip_tx_timeout): Add specific
- debugging for PNIC2.
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c (tulip_init_one): Print out
- tulip%d instead of PCI device number, for
- consistency.
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * Merge changes from Becker's tulip.c:
- Fix bugs in ioctl.
- Fix several bugs by distinguishing between MII
- and SYM advertising values.
- Set CSR14 autonegotiation bit for media types 2 and 4,
- where the SIA CSR setup values are not provided.
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * media.c (tulip_select_media): Only update MII
- advertising value if startup arg < 2.
-
- * tulip.h: Do not enable CSR13/14/15 autoconfiguration
- for 21041.
-
- * tulip_core.c:
- 21041: add specific code for reset, and do not set CAC bit
- When resetting media, for media table type 11 media, pass
- value 2 as 'startup' arg to select_media, to avoid updating
- MII advertising value.
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * pnic.c (pnic_check_duplex): remove
- pnic.c (pnic_lnk_change, pnic_timer): use
- tulip_check_duplex not pnic_check_duplex.
-
- * media.c (tulip_check_duplex):
- Clean up to use symbolic names instead of numeric constants.
- Set TxThreshold mode as necessary as well as clearing it.
- Update csr6 if csr6 changes, not simply if duplex changes.
-
- (found by Manfred Spraul)
-
-2001-05-10 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * 21142.c, eeprom.c, tulip.h, tulip_core.c:
- Remove DPRINTK as another, better method of
- debug message printing is available.
-
-2001-05-09 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * 21142.c (t21142_lnk_change): Pass arg startup==1
- to tulip_select_media, in order to force csr13 to be
- zeroed out prior to going to full duplex mode. Fixes
- autonegotiation on a quad-port Znyx card.
- (from Stephen Dengler)
-
-2001-05-09 Russell King <rmk@arm.linux.org.uk>
-
- * interrupt.c: Better PCI bus error reporting.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c: Now that dev->name is only available late
- in the probe, insert a hack to replace a not-evaluated
- "eth%d" string with an evaluated "tulip%d" string.
- Also, remove obvious comment and an indentation cleanup.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c: If we are a module, always print out the
- version string. If we are built into the kernel, only print
- the version string if at least one tulip is detected.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- Merged from Becker's tulip.c 0.92t:
-
- * tulip_core.c: Add support for Conexant LANfinity.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c: Only suspend/resume if the interface
- is up and running. Use alloc_etherdev and pci_request_regions.
- Spelling fix.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c: Remove code that existed when one or more of
- the following defines existed. These defines were never used
- by normal users in practice: TULIP_FULL_DUPLEX,
- TULIP_DEFAULT_MEDIA, and TULIP_NO_MEDIA_SWITCH.
-
- * tulip.h, eeprom.c: Move EE_* constants from tulip.h to eeprom.c.
- * tulip.h, media.c: Move MDIO_* constants from tulip.h to media.c.
-
- * media.c: Add barrier() to mdio_read/write's PNIC status check
- loops.

-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- Merged from Becker's tulip.c 0.92t:
-
- * tulip.h: Add MEDIA_MASK constant for bounding medianame[]
- array lookups.
- * eeprom.c, media.c, timer.c, tulip_core.c: Use it.
-
- * media.c, tulip_core.c: mdio_{read,write} cleanup. Since this
- is called [pretty much] directly from ioctl, we mask
- read/write arguments to limit the values passed.
- Added mii_lock. Added comet_miireg2offset and better
- Comet-specific mdio_read/write code. Pay closer attention
- to the bits we set in ioctl. Remove spinlocks from ioctl,
- they are in mdio_read/write now. Use mask to limit
- phy number in tulip_init_one's MII scan.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- Merged from Becker's tulip.c 0.92t:

-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * timer.c: Do not call netif_carrier_{on,off}, it is not used in
- the main tree. Leave code in, disabled, as markers for future
- carrier notification.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- Merged from Becker's tulip.c 0.92t, except for the tulip.h
- whitespace cleanup:
-
- * interrupt.c: If Rx stops, make sure to update the
- multicast filter before restarting.
- * tulip.h: Add COMET_MAC_ADDR feature flag, clean up flags.

- Prefer to test COMET_MAC_ADDR flag to testing chip_id for COMET,
- when dealing with the Comet's MAC address.
- Enable Tx underrun recovery for Comet chips.
- Use new Accept* constants in set_rx_mode.
- Prefer COMET_MAC_ADDR flag test to chip_id test in set_rx_mode.
- Store built mc_filter for later use in intr handler by Comets.
-
-2001-04-03 Jeff Garzik <jgarzik@mandrakesoft.com>
-
- * tulip_core.c: Use tp->cur_tx when building the
- setup frame, instead of assuming that the setup
- frame is always built in slot zero. This case is
- hit during PM resume.

- new_csr6, all cases initialize it properly.
-
-2001-02-18 Manfred Spraul <manfred@colorfullife.com>
-
- * interrupt.c (tulip_refill_rx): Make public.
- If PNIC chip stops due to lack of Rx buffers, restart it.

- with software timers.
- * pnic.c (pnic_check_duplex): New function, PNIC-specific
- version of tulip_check_duplex.
- (pnic_lnk_change): Call pnic_check_duplex. If we use an
- external MII, then we mustn't use the internal negotiation.
- (pnic_timer): Support Rx refilling on work overflow in
- interrupt handler, as PNIC doesn't support a h/w timer.
