Description Michal Schmidt 2011-01-14 15:31:11 UTC 
The receive functions {napi,vlan}_gro_{frags,receive} in the RHEL kernel return NET_RX_* results. Most drivers do not care about the return value, but sfc would like to know the GRO result instead. Upstream changed it in:

    gro: Name the GRO result enumeration type

commit c7c4b3b6e976b95facbb723951bdcd554a3530a4
Author: Ben Hutchings <bhutchings>
Date:   Thu Oct 29 21:36:53 2009 -0700

    gro: Change all receive functions to return GRO result codes

We cannot do the same change in RHEL, because the functions are KABI. We can add new functions though.
