Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Handle max TX power properly wrt VIFs and the MAC in iwlwifi, from
Avri Altman.
2) Use the correct FW API for scan completions in iwlwifi, from Avraham
Stern.
3) FW monitor in iwlwifi accidently uses unmapped memory, fix from Liad
Kaufman.
4) rhashtable conversion of mac80211 station table was buggy, the
virtual interface was not taken into account. Fix from Johannes
Berg.
5) Fix deadlock in rtlwifi by not using a zero timeout for
usb_control_msg(), from Larry Finger.
6) Update reordering state before calculating loss detection, from
Yuchung Cheng.
7) Fix off by one in bluetooth firmward parsing, from Dan Carpenter.
8) Fix extended frame handling in xiling_can driver, from Jeppe
Ledet-Pedersen.
9) Fix CODEL packet scheduler behavior in the presence of TSO packets,
from Eric Dumazet.
10) Fix NAPI budget testing in fm10k driver, from Alexander Duyck.
11) macvlan needs to propagate promisc settings down the the lower
device, from Vlad Yasevich.
12) igb driver can oops when changing number of rings, from Toshiaki
Makita.
13) Source specific default routes not handled properly in ipv6, from
Markus Stenberg.
14) Use after free in tc_ctl_tfilter(), from WANG Cong.
15) Use softirq spinlocking in netxen driver, from Tony Camuso.
16) Two ARM bpf JIT fixes from Nicolas Schichan.
17) Handle MSG_DONTWAIT properly in ring based AF_PACKET sends, from
Mathias Kretschmer.
18) Fix x86 bpf JIT implementation of FROM_{BE16,LE16,LE32}, from Alexei
Starovoitov.
19) ll_temac driver DMA maps TX packet header with incorrect length, fix
from Michal Simek.
20) We removed pm_qos bits from netdevice.h, but some indirect
references remained. Kill them. From David Ahern.
