Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"This looks like a lot but it's a mixture of regression fixes as well
as fixes for longer standing issues.
1) Fix on-channel cancellation in mac80211, from Johannes Berg.
2) Handle CHECKSUM_COMPLETE properly in xt_TCPMSS netfilter xtables
module, from Eric Dumazet.
3) Avoid infinite loop in UDP SO_REUSEPORT logic, also from Eric
Dumazet.
4) Avoid a NULL deref if we try to set SO_REUSEPORT after a socket is
bound, from Craig Gallek.
5) GRO key comparisons don't take lightweight tunnels into account,
from Jesse Gross.
6) Fix struct pid leak via SCM credentials in AF_UNIX, from Eric
Dumazet.
7) We need to set the rtnl_link_ops of ipv6 SIT tunnels before we
register them, otherwise the NEWLINK netlink message is missing
the proper attributes. From Thadeu Lima de Souza Cascardo.
8) Several Spectrum chip bug fixes for mlxsw switch driver, from Ido
Schimmel
9) Handle fragments properly in ipv4 easly socket demux, from Eric
Dumazet.
10) Don't ignore the ifindex key specifier on ipv6 output route
lookups, from Paolo Abeni"
