Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) In order to avoid problems in the future, make cgroup bpf overriding
explicit using BPF_F_ALLOW_OVERRIDE. From Alexei Staovoitov.
2) LLC sets skb->sk without proper skb->destructor and this explodes,
fix from Eric Dumazet.
3) Make sure when we have an ipv4 mapped source address, the
destination is either also an ipv4 mapped address or
ipv6_addr_any(). Fix from Jonathan T. Leighton.
4) Avoid packet loss in fec driver by programming the multicast filter
more intelligently. From Rui Sousa.
5) Handle multiple threads invoking fanout_add(), fix from Eric
Dumazet.
6) Since we can invoke the TCP input path in process context, without
BH being disabled, we have to accomodate that in the locking of the
TCP probe. Also from Eric Dumazet.
7) Fix erroneous emission of NETEVENT_DELAY_PROBE_TIME_UPDATE when we
aren't even updating that sysctl value. From Marcus Huewe.
8) Fix endian bugs in ibmvnic driver, from Thomas Falcon.
[ This is the second version of the pull that reverts the nested
rhashtable changes that looked a bit too scary for this late in the
release - Linus ]
