From: Eric Dumazet <edumazet@google.com> napi_gro_receive() can never return GRO_DROP GRO_DROP can only be returned from napi_gro_frags() which is the other NAPI GRO entry point. Followup patch will remove GRO_DROP, because drivers are not supposed to call napi_gro_frags() if prior napi_get_frags() has failed. Note that I have left the gro_dropped variable. I leave to ice maintainers the decision to further remove it from ethtool -S results. Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Jesse Brandeburg <redacted>
Acked-by: Jesse Brandeburg <redacted> Jakub or David, you're welcome to apply directly as part of this series. The original code went into the kernel right as the code to remove GRO_DROP returns went in just before, but the reviews crossed each other and no-one (especially me :-( ) caught it. for reference: commit 0e00c05fa72554c86d7c7e0f538ec83bfe277c91 Merge: b18e9834f7b2 045790b7bc66 Author: David S.
