<div class='commit-subject'>Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net</div><div class='commit-msg'>Pull networking fixes from David Miller:

 1) Load correct firmware in rtl8192ce wireless driver, from Jurij
    Smakov.

 2) Fix leak of tx_ring and tx_cq due to overwriting in mlx4 driver,
    from Martin KaFai Lau.

 3) Need to reference count PHY driver module when it is attached, from
    Mao Wenan.

 4) Don't do zero length vzalloc() in ethtool register dump, from
    Stanislaw Gruszka.

 5) Defer net_disable_timestamp() to a workqueue to get out of locking
    issues, from Eric Dumazet.

 6) We cannot drop the SKB dst when IP options refer to them, fix also
    from Eric Dumazet.

 7) Incorrect packet header offset calculations in ip6_gre, again from
    Eric Dumazet.

 8) Missing tcp_v6_restore_cb() causes use-after-free, from Eric too.

 9) tcp_splice_read() can get into an infinite loop with URG, and hey
    it's from Eric once more.

10) vnet_hdr_sz can change asynchronously, so read it once during
    decision making in macvtap and tun, from Willem de Bruijn.

11) Can't use kernel stack for DMA transfers in USB networking drivers,
    from Ben Hutchings.

12) Handle csum errors properly in UDP by calling the proper destructor,
    from Eric Dumazet.

13) For non-deterministic softirq run when scheduling NAPI from a
    workqueue in mlx4, from Benjamin Poirier.
