Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networkign fixes from David Miller:
"Networking bug fixes, Cacio e Pepe edition:
1) BNX2X accidently accesses chip rev specific registers without an
appropriate guard, fix from Ariel Elior.
2) When we removed the routing cache, we set ip_rt_max_size to ~0 just
to keep reporting a value to userspace via sysfs. But the ipv4
IPSEC layer was using this to tune itself which is completely bogus
to now do. Fix from Steffen Klassert.
3) Missing initialization in netfilter ipset code from Jozsef
Kadlecsik.
4) Check CTA_TIMEOUT_NAME length properly in netfilter cttimeout code,
fix from Florian Westphal.
5) After removing the routing cache, we inadvertantly are caching
multicast routes that end up looping back locally, we cannot do
that legitimately any more. Fix from Julian Anastasov.
6) Revert a race fix for 8139cp qemu/kvm that doesn't actually work
properly on real hardware. From Francois Romieu.
7) Fixup errors in example command lines in VXLAN device docs."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
bnx2x: remove redundant warning log
vxlan: fix command usage in its doc
8139cp: revert "set ring address before enabling receiver"
ipv4: do not cache looped multicasts
netfilter: cttimeout: fix buffer overflow
netfilter: ipset: Fix range bug in hash:ip,port,net
xfrm: Fix the gc threshold value for ipv4
