Pull networking fixes from David Miller:

 1) Fix PCI IDs of 9000 series iwlwifi devices, from Luca Coelho.

 2) bpf offload bug fixes from Jakub Kicinski.

 3) Fix bpf verifier to NOP out code which is dead at run time because
    due to branch pruning the verifier will not explore such
    instructions. From Alexei Starovoitov.

 4) Fix crash when deleting secondary chains in packet scheduler
    classifier. From Roman Kapl.

 5) Fix buffer management bugs in smc, from Ursula Braun.

 6) Fix regression in anycast route handling, from David Ahern.

 7) Fix link settings regression in r8169, from Tobias Jakobi.

 8) Add back enough UFO support so that live migration still works, from
    Willem de Bruijn.

 9) Linearize enough packet data for the full extent to which the ipvlan
    code will inspect the packet headers, from Gao Feng.
