From e87eb4051efe76b35d0a297db772f5964a001544 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 15 Oct 2015 09:22:11 -0700 Subject: [PATCH] bonding: support encapsulated ipv6 TSO If using a sixtofour device on top of a bonding device, skb segmentation of TCP traffic is done right before calling bonding xmit, because bonding only enables TSO for IPv4. This patch improves single flow performance by about 120 % on my hosts, because segmentation is deferred right before calling slave xmit. Signed-off-by: Eric Dumazet Signed-off-by: David S.
