From c7c4b3b6e976b95facbb723951bdcd554a3530a4 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 29 Oct 2009 21:36:53 -0700 Subject: gro: Change all receive functions to return GRO result codes This will allow drivers to adjust their receive path dynamically based on whether GRO is being applied successfully. Currently all in-tree callers ignore the return values of these functions and do not need to be changed. Signed-off-by: Ben Hutchings Acked-by: Herbert Xu Signed-off-by: David S.
