From 1d04cd4e722c63e8d5564c6c993b04a891f1e867 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Mon, 16 Dec 2013 17:03:45 -0800 Subject: [PATCH] datapath: Compute checksum in skb_gso_segment() if needed The copy & csum optimization is no longer present with zerocopy enabled. Compute the checksum in skb_gso_segment() directly by dropping the HW CSUM capability from the features passed in.
