Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"Two stragglers:
1) The new code that adds new flushing semantics to GRO can cause SKB
pointer list corruption, manage the lists differently to avoid the
OOPS. Fix from Eric Dumazet.
2) When TCP fast open does a retransmit of data in a SYN-ACK or
similar, we update retransmit state that we shouldn't triggering a
WARN_ON later. Fix from Yuchung Cheng."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
net: gro: fix possible panic in skb_gro_receive()
tcp: bug fix Fast Open client retransmission
