Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking changes from David S. Miller:

 1) Fix IPSEC header length calculation for transport mode in ESP.  The
    issue is whether to do the calculation before or after alignment.
    Fix from Benjamin Poirier.

 2) Fix regression in IPV6 IPSEC fragment length calculations, from Gao
    Feng.  This is another transport vs tunnel mode issue.

 3) Handle AF_UNSPEC connect()s properly in L2TP to avoid OOPSes.  Fix
    from James Chapman.

 4) Fix USB ASIX driver's reception of full sized VLAN packets, from
    Eric Dumazet.

 5) Allow drop monitor (and, more generically, all generic netlink
    protocols) to be automatically loaded as a module.  From Neil
    Horman.

Fix up trivial conflict in Documentation/feature-removal-schedule.txt
due to new entries added next to each other at the end. As usual.
