Subject: [PATCH net-next 0/2] net: small csum optimizations

From: Eric Dumazet <edumazet@...gle.com>

After recent x86 csum_partial() optimizations, we can more easily
see in kernel profiles costs of add/adc operations that could
be avoided, by feeding a non zero third argument to csum_partial()

Eric Dumazet (2):
  gro: optimize skb_gro_postpull_rcsum()
  net: optimize skb_postpull_rcsum()
