[NET] net-gso.patch: Fix up GSO packets with broken checksums

Here is the original changelog:

   [NET] gso: Fix up GSO packets with broken checksums

   Certain subsystems in the stack (e.g., netfilter) can break the
   partial
   checksum on GSO packets.  Until they're fixed, this patch allows
   this to
   work by recomputing the partial checksums through the GSO
   mechanism.

   Once they've all been converted to update the partial checksum
   instead of
   clearing it, this workaround can be removed.
