From 5f114163f2f5eb2edbb49c4d3e0b405c7a8a7e2a Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 15 Feb 2017 09:39:39 +0100 Subject: net: Add a skb_gro_flush_final helper. Add a skb_gro_flush_final helper to prepare for consuming skbs in call_gro_receive. We will extend this helper to not touch the skb if the skb is consumed by a gro callback with a followup patch. We need this to handle the upcomming IPsec ESP callbacks as they reinject the skb to the napi_gro_receive asynchronous. The handler is used in all gro_receive functions that can call the ESP gro handlers.
