Pull networking fixes from David Miller:

 1) Fix several bpfilter/UMH bugs, in particular make the UMH build not
    depend upon X86 specific Kconfig symbols. From Alexei Starovoitov.

 2) Fix handling of modified context pointer in bpf verifier, from
    Daniel Borkmann.

 3) Kill regression in ifdown/ifup sequences for hv_netvsc driver, from
    Dexuan Cui.

 4) When the bonding primary member name changes, we have to re-evaluate
    the bond->force_primary setting, from Xiangning Yu.

 5) Eliminate possible padding beyone end of SKB in cdc_ncm driver, from
    Bjørn Mork.

 6) RX queue length reported for UDP sockets in procfs and socket diag
    are inaccurate, from Paolo Abeni.

 7) Fix br_fdb_find_port() locking, from Petr Machata.

 8) Limit sk_rcvlowat values properly in TCP, from Soheil Hassas
    Yeganeh.
