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

Pull networking fixes from David Miller:

 1) Don't use MMIO on certain iwlwifi devices otherwise we get a
    firmware crash.

 2) Don't corrupt the GRO lists of mac80211 contexts by doing sends via
    timer interrupt, from Johannes Berg.

 3) SKB tailroom is miscalculated in AP_VLAN crypto code, from Michal
    Kazior.

 4) Fix fw_status memory leak in iwlwifi, from Haim Dreyfuss.

 5) Fix use after free in iwl_mvm_d0i3_enable_tx(), from Eliad Peller.

 6) JIT'ing of large BPF programs is broken on x86, from Alexei
    Starovoitov.

 7) EMAC driver ethtool register dump size is miscalculated, from Ivan
    Mikhaylov.

 8) Fix PHY initial link mode when autonegotiation is disabled in
    amd-xgbe, from Tom Lendacky.

 9) Fix NULL deref on SOCK_DEAD socket in AF_UNIX and CAIF protocols,
    from Mark Salyzyn.

10) credit_bytes not initialized properly in xen-netback, from Ross
   Lagerwall.

11) Fallback from MSI-X to INTx interrupts not handled properly in mlx4
    driver, fix from Benjamin Poirier.

12) Perform ->attach() after binding dev->qdisc in packet scheduler,
    otherwise we can crash.  From Cong WANG.

13) Don't clobber data in sctp_v4_map_v6().  From Jason Gunthorpe.
