Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Fix double SKB free in bluetooth 6lowpan layer, from Jukka Rissanen.
2) Fix receive checksum handling in enic driver, from Govindarajulu
Varadarajan.
3) Fix NAPI poll list corruption in virtio_net and caif_virtio, from
Herbert Xu. Also, add code to detect drivers that have this mistake
in the future.
4) Fix doorbell endianness handling in mlx4 driver, from Amir Vadai.
5) Don't clobber IP6CB() before xfrm6_policy_check() is called in TCP
input path,f rom Nicolas Dichtel.
6) Fix MPLS action validation in openvswitch, from Pravin B Shelar.
7) Fix double SKB free in vxlan driver, also from Pravin.
8) When we scrub a packet, which happens when we are switching the
context of the packet (namespace, etc.), we should reset the
secmark. From Thomas Graf.
9) ->ndo_gso_check() needs to do more than return true/false, it also
has to allow the driver to clear netdev feature bits in order for
the caller to be able to proceed properly. From Jesse Gross.
