Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:

 1) Fix use-after-free in IPSEC input parsing, desintation address
    pointer was loaded before pskb_may_pull() which can change the SKB
    data pointers. From Florian Westphal.

 2) Stack out-of-bounds read in xfrm_state_find(), from Steffen
    Klassert.

 3) IPVS state of SKB is not properly reset when moving between
    namespaces, from Ye Yin.

 4) Fix crash in asix driver suspend and resume, from Andrey Konovalov.

 5) Don't deliver ipv6 l2tp tunnel packets to ipv4 l2tp tunnels, and
    vice versa, from Guillaume Nault.

 6) Fix DSACK undo on non-dup ACKs, from Priyaranjan Jha.

 7) Fix regression in bond_xmit_hash()'s behavior after the TCP port
    selection changes back in 4.2, from Hangbin Liu.

 8) Two divide by zero bugs in USB networking drivers when parsing
    descriptors, from Bjorn Mork.

 9) Fix bonding slaves being stuck in BOND_LINK_FAIL state, from Jay
    Vosburgh.

10) Missing skb_reset_mac_header() in qmi_wwan, from Kristian Evensen.

11) Fix the destruction of tc action object races properly, from Cong
    Wang.
