Pull networking fixes from David Miller:

 1) Need to access netdev->num_rx_queues behind an accessor in netvsc
    driver otherwise the build breaks with some configs, from Arnd
    Bergmann.

 2) Add dummy xfrm_dev_event() so that build doesn't fail when
    CONFIG_XFRM_OFFLOAD is not set. From Hangbin Liu.

 3) Don't OOPS when pfkey_msg2xfrm_state() signals an erros, from Dan
    Carpenter.

 4) Fix MCDI command size for filter operations in sfc driver, from
    Martin Habets.

 5) Fix UFO segmenting so that we don't calculate incorrect checksums,
    from Michal Kubecek.

 6) When ipv6 datagram connects fail, reset destination address and
    port. From Wei Wang.

 7) TCP disconnect must reset the cached receive DST, from WANG Cong.

 8) Fix sign extension bug on 32-bit in dev_get_stats(), from Eric
    Dumazet.

 9) fman driver has to depend on HAS_DMA, from Madalin Bucur.

10) Fix bpf pointer leak with xadd in verifier, from Daniel Borkmann.

11) Fix negative page counts with GFO, from Michal Kubecek.
