Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Fix regression allowing IP_TTL setting of zero, fix from Cong Wang.
2) Fix leak regressions in tunap, from Jason Wang.
3) be2net driver always returns IRQ_HANDLED in INTx handler, fix from
Sathya Perla.
4) qlge doesn't really support NETIF_F_TSO6, don't set that flag. Fix
from Amerigo Wang.
5) Add 802.11ad Atheros wil6210 driver, from Vladimir Kondratiev.
6) Fix MTU calculations in mac80211 layer, from T Krishna Chaitanya.
7) Station info layer of mac80211 needs to use del_timer_sync(), from
Johannes Berg.
8) tcp_read_sock() can loop forever, because we don't immediately stop
when recv_actor() returns zero. Fix from Eric Dumazet.
9) Fix WARN_ON() in tcp_cleanup_rbuf(). We have to use sk_eat_skb() in
tcp_recv_skb() to handle the case where a large GRO packet is split
up while it is use by a splice() operation. Fix also from Eric
Dumazet.
10) addrconf_get_prefix_route() in ipv6 tests flags incorrectly, it
does:
if (X && (p->flags & Y) != 0)
when it really meant to go:
if (X && (p->flags & X) != 0)
fix from Romain Kuntz.
11) Fix lost Kconfig dependency for bfin_mac driver hardware
timestamping. From Lars-Peter Clausen.
12) Fix regression in handling of RST without ACK in TCP, from Eric
Dumazet.
