+IP: virtual server support
+CONFIG_IP_VS
+ IP Virtual Server support will let you build a high-performance
+ virtual server based on cluster of two or more real servers. This
+ option must be enabled for at least one of the clustered computers
+ that will take care of intercepting incomming connections to a
+ single IP address and scheduling them to real servers.
+
+ Three request dispatching techniques are implemented, they are
+ virtual server via NAT, virtual server via tunneling and virtual
+ server via direct routing. The several scheduling algorithms can
+ be used to choose which server the connection is directed to,
+ thus load balancing can be achieved among the servers. For more
+ information and its administration program, please visit the
+ following URL:
+ http://www.linuxvirtualserver.org/
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IP virtual server debugging
+CONFIG_IP_VS_DEBUG
+ Say Y here if you want to get additional messages useful in
+ debugging the IP virtual server code. You can change the debug
+ level in /proc/sys/net/ipv4/vs/debug_level
+
+IPVS connection hash table size (the Nth power of 2)
+CONFIG_IP_VS_TAB_BITS
+ The IPVS connection hash table uses the chaining scheme to handle
+ hash collisions. Using a big IPVS connection hash table will greatly
+ reduce conflicts when there are hundreds of thousands of connections
+ in the hash table.
+
+ Note the table size must be power of 2. The table size will be the
+ value of 2 to the your input number power. The number to choose is
+ from 8 to 20, the default number is 12, which means the table size
+ is 4096. Don't input the number too small, otherwise you will lose
+ performance on it. You can adapt the table size yourself, according
+ to your virtual server application. It is good to set the table size
+ not far less than the number of connections per second multiplying
+ average lasting time of connection in the table. For example, your
+ virtual server gets 200 connections per second, the connection lasts
+ for 200 seconds in average in the connection table, the table size
+ should be not far less than 200x200, it is good to set the table
+ size 32768 (2**15).
+
+ Another note that each connection occupies 128 bytes effectively and
+ each hash entry uses 8 bytes, so you can estimate how much memory is
+ needed for your box.
+
+IPVS: round-robin scheduling
+CONFIG_IP_VS_RR
+ The robin-robin scheduling algorithm simply directs network
+ connections to different real servers in a round-robin manner.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: weighted round-robin scheduling
+CONFIG_IP_VS_WRR
+ The weighted robin-robin scheduling algorithm directs network
+ connections to different real servers based on server weights
+ in a round-robin manner. Servers with higher weights receive
+ new connections first than those with less weights, and servers
+ with higher weights get more connections than those with less
+ weights and servers with equal weights get equal connections.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: least-connection scheduling
+CONFIG_IP_VS_LC

+ connections to the server with the least number of active
+ connections.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: weighted least-connection scheduling
+CONFIG_IP_VS_WLC
+ The weighted least-connection scheduling algorithm directs network
+ connections to the server with the least active connections
+ normalized by the server weight.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: locality-based least-connection scheduling
+CONFIG_IP_VS_LBLC
+ The locality-based least-connection scheduling algorithm is for
+ destination IP load balancing. It is usually used in cache cluster.
+ This algorithm usually directs packet destined for an IP address to
+ its server if the server is alive and under load. If the server is
+ overloaded (its active connection numbers is larger than its weight)
+ and there is a server in its half load, then allocate the weighted
+ least-connection server to this IP address.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: locality-based least-connection with replication scheduling
+CONFIG_IP_VS_LBLCR
+ The locality-based least-connection with replication scheduling
+ algorithm is also for destination IP load balancing. It is
+ usually used in cache cluster. It differs from the LBLC scheduling
+ as follows: the load balancer maintains mappings from a target
+ to a set of server nodes that can serve the target. Requests for
+ a target are assigned to the least-connection node in the target's
+ server set. If all the node in the server set are over loaded,
+ it picks up a least-connection node in the cluster and adds it
+ in the sever set for the target. If the server set has not been
+ modified for the specified time, the most loaded node is removed
+ from the server set, in order to avoid high degree of replication.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: destination hashing scheduling
+CONFIG_IP_VS_DH
+ The destination hashing scheduling algorithm assigns network
+ connections to the servers through looking up a statically assigned
+ hash table by their destination IP addresses.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: source hashing scheduling
+CONFIG_IP_VS_SH
+ The source hashing scheduling algorithm assigns network
+ connections to the servers through looking up a statically assigned
+ hash table by their source IP addresses.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: shortest expected delay scheduling
+CONFIG_IP_VS_SED
+ The shortest expected delay scheduling algorithm assigns network
+ connections to the server with the shortest expected delay. The
+ expected delay that the job will experience is (Ci + 1) / Ui if
+ sent to the ith server, in which Ci is the number of connections
+ on the the ith server and Ui is the fixed service rate (weight)
+ of the ith server.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: never queue scheduling
+CONFIG_IP_VS_NQ
+ The never queue scheduling algorithm adopts a two-speed model.
+ When there is an idle server available, the job will be sent to
+ the idle server, instead of waiting for a fast one. When there
+ is no idle server available, the job will be sent to the server
+ that minimize its expected delay (The Shortest Expected Delay
+ scheduling algorithm).
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.
+
+IPVS: FTP protocol helper
+CONFIG_IP_VS_FTP
+ FTP is a protocol that transfers IP address and/or port number in
+ the payload. In the virtual server via Network Address Translation,
+ the IP address and port number of real servers cannot be sent to
+ clients in ftp connections directly, so FTP protocol helper is
+ required for tracking the connection and mangling it back to that of
+ virtual service.
+
+ If you want to compile it in kernel, say Y. If you want to compile
+ it as a module, say M here and read Documentation/modules.txt. If
+ unsure, say N.

+CONFIG_USB_GADGET
+ USB is a master/slave protocol, organized with one master
+ host (such as a PC) controlling up to 127 peripheral devices.
+ The USB hardware is asymmetric, which makes it easier to set up:
+ you can't connect two "to-the-host" connectors to each other.
+
+ Linux can run in the host, or in the peripheral. In both cases
+ you need a low level bus controller driver, and some software
+ talking to it. Peripheral controllers are often discrete silicon,
+ or are integrated with the CPU in a microcontroller. The more
+ familiar host side controllers have names like like "EHCI", "OHCI",
+ or "UHCI", and are usually integrated into southbridges on PC
+ motherboards.
+
+ Enable this configuration option if you want to run Linux inside
+ a USB peripheral device. Configure one hardware driver for your
+ peripheral/device side bus controller, and a "gadget driver" for
+ your peripheral protocol. (If you use modular gadget drivers,
+ you may configure more than one.)
+
+ If in doubt, say "N" and don't enable these drivers; most people
+ don't have this kind of hardware (except maybe inside Linux PDAs).
+
+CONFIG_USB_NET2280
+ NetChip 2280 is a PCI based USB peripheral controller which
+ supports both full and high speed USB 2.0 data transfers.
+
+ It has six configurable endpoints, as well as endpoint zero
+ (for control transfers) and several endpoints with dedicated
+ functions.
+
+ Say "y" to link the driver statically, or "m" to build a
+ dynamically linked module called "net2280" and force all
+ gadget drivers to also be dynamically linked.
+
+CONFIG_USB_ZERO
+ Gadget Zero is a two-configuration device. It either sinks and
+ sources bulk data; or it loops back a configurable number of
+ transfers. It also implements control requests, for "chapter 9"
+ conformance. The driver needs only two bulk-capable endpoints, so
+ it can work on top of most device-side usb controllers. It's
+ useful for testing, and is also a working example showing how
+ USB "gadget drivers" can be written.
+
+ Make this be the first driver you try using on top of any new
+ USB peripheral controller driver. Then you can use host-side
+ test software, like the "usbtest" driver, to put your hardware
+ and its driver through a basic set of functional tests.
+
+ Gadget Zero also works with the host-side "usb-skeleton" driver,
+ and with many kinds of host-side test software. You may need
+ to tweak product and vendor IDs before host software knows about
+ this device, and arrange to select an appropriate configuration.
+
+ Say "y" to link the driver statically, or "m" to build a
+ dynamically linked module called "g_zero".
+
+CONFIG_USB_ETH
+ This driver implements Ethernet style communication, in either
+ of two ways:
+
+ - The "Communication Device Class" (CDC) Ethernet Control Model.
+ That protocol is often avoided with pure Ethernet adapters, in
+ favor of simpler vendor-specific hardware, but is widely
+ supported by firmware for smart network devices.
+
+ - On hardware can't implement that protocol, a simpler approach
+ is used, placing fewer demands on USB.
+
+ Within the USB device, this gadget driver exposes a network device
+ "usbX", where X depends on what other networking devices you have.
+ Treat it like a two-node Ethernet link: host, and gadget.
+
+ The Linux-USB host-side "usbnet" driver interoperates with this
+ driver, so that deep I/O queues can be supported. On 2.4 kernels,
+ use "CDCEther" instead, if you're using the CDC option. That CDC
+ mode should also interoperate with standard CDC Ethernet class
+ drivers on other host operating systems.
+
+ Say "y" to link the driver statically, or "m" to build a
+ dynamically linked module called "g_ether".

+
+PowerPC 405 on-chip ethernet -- Amount of bytes to Reserve on a skb
+CONFIG_IBM_OCP_ENET_SKB_RES
+ Many standard ethernet drivers need to reserve 2 bytes of data
+ on the skb before giving the data ptr to the hardware. This is
+ so the IP data will be 16-byte aligned when it goes up the stack.
+ This is a requirement for some processors and it can cause major
+ slow downs on others. The 405GP dose not have problems with the
+ misaligned data so the default is 0. If you need to route the
+ incoming ethernet packets to another device that has alignment
+ requirements this can help remove a data copy. A value of 2 can
+ help at getting 16-byte aligned IP data for another device. A
+ larger value can be used when routing to a IP tunnel device.
+ Make sure XXX_DESC_SIZE - XXX_SKB_RES >= 1514, or larger if VLANS
+ are used.
