Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix refcounting wrt timers which hold onto inet6 address objects, from Xin Long. 2) Fix an ancient bug in wireless wext ioctls, from Johannes Berg. 3) Firmware handling fixes in brcm80211 driver, from Arend Van Spriel. 4) Several mlx5 driver fixes (firmware readiness, timestamp cap reporting, devlink command validity checking, tc offloading, etc.) From Eli Cohen, Maor Dickman, Chris Mi, and Or Gerlitz. 5) Fix dst leak in IP/IP6 tunnels, from Haishuang Yan. 6) Fix dst refcount bug in decnet, from Wei Wang. 7) Netdev can be double freed in register_vlan_device(). Fix from Gao Feng. 8) Don't allow object to be destroyed while it is being dumped in SCTP, from Xin Long. 9) Fix dpaa_eth build when modular, from Madalin Bucur. 10) Fix throw route leaks, from Serhey Popovych. 11) IFLA_GROUP missing from if_nlmsg_size() and ifla_policy[] table, also from Serhey Popovych. 12) Fix premature TX SKB free in stmmac, from Niklas Cassel. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (36 commits) igmp: add a missing spin_lock_init() net: stmmac: free an skb first when there are no longer any descriptors using it sfc: remove duplicate up_write on VF filter_sem rtnetlink: add IFLA_GROUP to ifla_policy ipv6: Do not leak throw route references dt-bindings: net: sms911x: Add missing optional VDD regulators dpaa_eth: reuse the dma_ops provided by the FMan MAC device fsl/fman: propagate dma_ops net/core: remove explicit do_softirq() from busy_poll_stop() fib_rules: Resolve goto rules target on delete sctp: ensure ep is not destroyed before doing the dump net/hns:bugfix of ethtool -t phy self_test net: 8021q: Fix one possible panic caused by BUG_ON in free_netdev cxgb4: notify uP to route ctrlq compl to rdma rspq ip6_tunnel: Correct tos value in collect_md mode decnet: always not take dst->__refcnt when inserting dst into hash table ip6_tunnel: fix potential issue in __ip6_tnl_rcv ip_tunnel: fix potential issue in ip_tunnel_rcv brcmfmac: fix uninitialized warning in brcmf_usb_probe_phase2() net/mlx5e: Avoid doing a cleanup call if the profile doesn't have it ...
