Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
1) VETH_INFO_PEER netlink attribute needs to have it's size validated,
from Thomas Graf.
2) 'poll' module option of bnx2x driver crashes the machine, just remove
it. From Michal Schmidt.
3) ks8851_mll driver reads the irq number from two places, but only
initializes one of them, oops. Use only one location and fix this
problem, from Jan Weitzel.
4) Fix buffer overrun and unicast sterring bugs in mellanox mlx4 driver,
from Eugenia Emantayev.
5) Swapped kcalloc() args in RxRPC and mlx4, from Axel Lin.
6) PHY MDIO device name regression fixes from Florian Fainelli.
7) If the wake event IRQ line is different from the netdevice one, we
have to properly route it to the stmmac interrupt handler. From
Francesco Virlinzi.
8) Fix rwlock lock initialization ordering bug in mac80211, from
Mohammed Shafi Shajakhan.
9) TCP lost_cnt can get out of sync, and in fact go negative, in certain
circumstances. Fix the way we specify what sequence range to operate
on in tcp_sacktag_one() to fix this bug. From Neal Cardwell.
