Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Fix ordering of WEXT netlink messages so we don't see a newlink
after a dellink, from Johannes Berg.
2) Out of bounds access in minstrel_ht_set_best_prob_rage, from
Konstantin Khlebnikov.
3) Paging buffer memory leak in iwlwifi, from Matti Gottlieb.
4) Wrong units used to set initial TCP rto from cached metrics, also
from Konstantin Khlebnikov.
5) Fix stale IP options data in the SKB control block from leaking
through layers of encapsulation, from Bernie Harris.
6) Zero padding len miscalculated in bnxt_en, from Michael Chan.
7) Only CHECKSUM_PARTIAL packets should be passed down through GSO, fix
from Hannes Frederic Sowa.
8) Fix suspend/resume with JME networking devices, from Diego Violat
and Guo-Fu Tseng.
9) Checksums not validated properly in bridge multicast support due to
the placement of the SKB header pointers at the time of the check,
fix from Álvaro Fernández Rojas.
10) Fix hang/tiemout with r8169 if a stats fetch is done while the
device is runtime suspended. From Chun-Hao Lin.
11) The forwarding database netlink dump facilities don't track the
state of the dump properly, resulting in skipped/missed entries.
From Minoura Makoto.
12) Fix regression from a recent 3c59x bug fix, from Neil Horman.
13) Fix list corruption in bna driver, from Ivan Vecera.
14) Big endian machines crash on vlan add in bnx2x, fix from Michal
Schmidt.
15) Ethtool RSS configuration not propagated properly in mlx5 driver,
from Tariq Toukan.
16) Fix regression in PHY probing in stmmac driver, from Gabriel
Fernandez.
17) Fix SKB tailroom calculation in igmp/mld code, from Benjamin
Poirier.
18) A past change to skip empty routing headers in ipv6 extention header
parsing accidently caused fragment headers to not be matched any
longer. Fix from Florian Westphal.
19) eTSEC-106 erratum needs to be applied to more gianfar chips, from
Atsushi Nemoto.
20) Fix netdev reference after free via workqueues in usb networking
drivers, from Oliver Neukum and Bjørn Mork.
21) mdio->irq is now an array rather than a pointer to dynamic memory,
but several drivers were still trying to free it :-/ Fixes from
Colin Ian King.
22) act_ipt iptables action forgets to set the family field, thus LOG
netfilter targets don't work with it. Fix from Phil Sutter.
23) SKB leak in ibmveth when skb_linearize() fails, from Thomas Falcon.
24) pskb_may_pull() cannot be called with interrupts disabled, fix code
that tries to do this in vmxnet3 driver, from Neil Horman.
25) be2net driver leaks iomap'd memory on removal, fix from Douglas
Miller.
26) Forgotton RTNL mutex unlock in ppp_create_interface() error paths,
from Guillaume Nault.
