Pull networking fixes from David Miller:

 1) Unbreak zebra and other netlink apps, from Eric W Biederman.

 2) Some new qmi_wwan device IDs, from Aleksander Morgado.

 3) Fix info leak in DCB netlink handler of qlcnic driver, from Dan
    Carpenter.

 4) inet_getid() and ipv6_select_ident() do not generate monotonically
    increasing ID numbers, fix from Eric Dumazet.

 5) Fix memory leak in __sk_prepare_filter(), from Leon Yu.

 6) Netlink leftover bytes warning message is user triggerable, rate
    limit it.  From Michal Schmidt.

 7) Fix non-linear SKB panic in ipvs, from Peter Christensen.

 8) Congestion window undo needs to be performed even if only never
    retransmitted data is SACK'd, fix from Yuching Cheng.
