Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Buffers powersave frame test is reversed in cfg80211, fix from Felix Fietkau. 2) Remove bogus WARN_ON in openvswitch, from Jarno Rajahalme. 3) Fix some tg3 ethtool logic bugs, and one that would cause no interrupts to be generated when rx-coalescing is set to 0. From Satish Baddipadige and Siva Reddy Kallam. 4) QLCNIC mailbox corruption and napi budget handling fix from Manish Chopra. 5) Fix fib_trie logic when walking the trie during /proc/net/route output than can access a stale node pointer. From David Forster. 6) Several sctp_diag fixes from Phil Sutter. 7) PAUSE frame handling fixes in mlxsw driver from Ido Schimmel. 8) Checksum fixup fixes in bpf from Daniel Borkmann. 9) Memork leaks in nfnetlink, from Liping Zhang. 10) Use after free in rxrpc, from David Howells. 11) Use after free in new skb_array code of macvtap driver, from Jason Wang. 12) Calipso resource leak, from Colin Ian King. 13) mediatek bug fixes (missing stats sync init, etc.) from Sean Wang. 14) Fix bpf non-linear packet write helpers, from Daniel Borkmann. 15) Fix lockdep splats in macsec, from Sabrina Dubroca. 16) hv_netvsc bug fixes from Vitaly Kuznetsov, mostly to do with VF handling. 17) Various tc-action bug fixes, from CONG Wang. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (116 commits) net_sched: allow flushing tc police actions net_sched: unify the init logic for act_police net_sched: convert tcf_exts from list to pointer array net_sched: move tc offload macros to pkt_cls.h net_sched: fix a typo in tc_for_each_action() net_sched: remove an unnecessary list_del() net_sched: remove the leftover cleanup_a() mlxsw: spectrum: Allow packets to be trapped from any PG mlxsw: spectrum: Unmap 802.1Q FID before destroying it mlxsw: spectrum: Add missing rollbacks in error path mlxsw: reg: Fix missing op field fill-up mlxsw: spectrum: Trap loop-backed packets mlxsw: spectrum: Add missing packet traps mlxsw: spectrum: Mark port as active before registering it mlxsw: spectrum: Create PVID vPort before registering netdevice mlxsw: spectrum: Remove redundant errors from the code mlxsw: spectrum: Don't return upon error in removal path i40e: check for and deal with non-contiguous TCs ixgbe: Re-enable ability to toggle VLAN filtering ixgbe: Force VLNCTRL.VFE to be set in all VMDq paths ...
