Pull networking fixes from David Miller: 1) Don't use shared bluetooth antenna in iwlwifi driver for management frames, from Emmanuel Grumbach. 2) Fix device ID check in ath9k driver, from Felix Fietkau. 3) Off by one in xen-netback BUG checks, from Dan Carpenter. 4) Fix IFLA_VF_PORT netlink attribute validation, from Daniel Borkmann. 5) Fix races in setting peeked bit flag in SKBs during datagram receive. If it's shared we have to clone it otherwise the value can easily be corrupted. Fix from Herbert Xu. 6) Revert fec clock handling change, causes regressions. From Fabio Estevam. 7) Fix use after free in fq_codel and sfq packet schedulers, from WANG Cong. 8) ipvlan bug fixes (memory leaks, missing rcu_dereference_bh, etc.) from WANG Cong and Konstantin Khlebnikov. 9) Memory leak in act_bpf packet action, from Alexei Starovoitov. 10) ARM bpf JIT bug fixes from Nicolas Schichan. 11) Fix backwards compat of ANY_LAYOUT in virtio_net driver, from Michael S Tsirkin. 12) Destruction of bond with different ARP header types not handled correctly, fix from Nikolay Aleksandrov. 13) Revert GRO receive support in ipv6 SIT tunnel driver, causes regressions because the GRO packets created cannot be processed properly on the GSO side if we forward the frame. From Herbert Xu. 14) TCCR update race and other fixes to ravb driver from Sergei Shtylyov. 15) Fix SKB leaks in caif_queue_rcv_skb(), from Eric Dumazet. 16) Fix panics on packet scheduler filter replace, from Daniel Borkmann. 17) Make sure AF_PACKET sees properly IP headers in defragmented frames (via PACKET_FANOUT_FLAG_DEFRAG option), from Edward Hyunkoo Jee. 18) AF_NETLINK cannot hold mutex in RCU callback, fix from Florian Westphal. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (84 commits) ravb: fix ring memory allocation net: phy: dp83867: Fix warning check for setting the internal delay openvswitch: allocate nr_node_ids flow_stats instead of num_possible_nodes netlink: don't hold mutex in rcu callback when releasing mmapd ring ARM: net: fix vlan access instructions in ARM JIT.
