Pull networking fixes from David Miller:

 1) Don't get per-cpu pointer with preemption enabled in nft_set_pipapo,
    fix from Stefano Brivio.

 2) Fix memory leak in ctnetlink, from Pablo Neira Ayuso.

 3) Multiple definitions of MPTCP_PM_MAX_ADDR, from Geliang Tang.

 4) Accidently disabling NAPI in non-error paths of macb_open(), from
    Charles Keepax.

 5) Fix races between alx_stop and alx_remove, from Zekun Shen.

 6) We forget to re-enable SRIOV during resume in bnxt_en driver, from
    Michael Chan.

 7) Fix memory leak in ipv6_mc_destroy_dev(), from Wang Hai.

 8) rxtx stats use wrong index in mvpp2 driver, from Sven Auhagen.

 9) Fix memory leak in mptcp_subflow_create_socket error path, from Wei
    Yongjun.

10) We should not adjust the TCP window advertised when sending dup acks
    in non-SACK mode, because it won't be counted as a dup by the sender
    if the window size changes. From Eric Dumazet.

11) Destroy the right number of queues during remove in mvpp2 driver,
    from Sven Auhagen.

12) Various WOL and PM fixes to e1000 driver, from Chen Yu, Vaibhav
    Gupta, and Arnd Bergmann.
