Pull networking fixes from David Miller:

 1) We've discovered a common error in several networking drivers, they
    put VLAN offload features into ->vlan_features, which would suggest
    that they support offloading 2 or more levels of VLAN encapsulation.
    Not only do these devices not do that, but we don't have the
    infrastructure yet to handle that at all.

    Fixes from Vlad Yasevich.

 2) Fix tcpdump crash with bridging and vlans, also from Vlad.

 3) Some MAINTAINERS updates for random32 and bonding.

 4) Fix late reseeds of prandom generator, from Sasha Levin.

 5) Bridge doesn't handle stacked vlans properly, fix from Toshiaki
    Makita.

 6) Fix deadlock in openvswitch, from Flavio Leitner.

 7) get_timewait4_sock() doesn't report delay times correctly, fix from
    Eric Dumazet.

 8) Duplicate address detection and addrconf verification need to run in
    contexts where RTNL can be obtained.  Move them to run from a
    workqueue.  From Hannes Frederic Sowa.

 9) Fix route refcount leaking in ip tunnels, from Pravin B Shelar.

10) Don't return -EINTR from non-blocking recvmsg() on AF_UNIX sockets,
    from Eric Dumazet.
