Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:

 1) Handle notifier registry failures properly in tun/tap driver, from
    Tonghao Zhang.

 2) Fix bpf verifier handling of subtraction bounds and add a testcase
    for this, from Edward Cree.

 3) Increase reset timeout in ftgmac100 driver, from Ben Herrenschmidt.

 4) Fix use after free in prd_retire_rx_blk_timer_exired() in AF_PACKET,
    from Cong Wang.

 5) Fix SElinux regression due to recent UDP optimizations, from Paolo
    Abeni.

 6) We accidently increment IPSTATS_MIB_FRAGFAILS in the ipv6 code
    paths, fix from Stefano Brivio.

 7) Fix some mem leaks in dccp, from Xin Long.

 8) Adjust MDIO_BUS kconfig deps to avoid build errors, from Arnd
    Bergmann.

 9) Mac address length check and buffer size fixes from Cong Wang.

10) Don't leak sockets in ipv6 udp early demux, from Paolo Abeni.

11) Fix return value when copy_from_user() fails in
    bpf_prog_get_info_by_fd(), from Daniel Borkmann.

12) Handle PHY_HALTED properly in phy library state machine, from
    Florian Fainelli.

13) Fix OOPS in fib_sync_down_dev(), from Ido Schimmel.

14) Fix truesize calculation in virtio_net which led to performance
    regressions, from Michael S Tsirkin.
