Pull networking fixes from David Miller:

 1) NLA_PUT* --> nla_put_* conversion got one case wrong in
    nfnetlink_log, fix from Patrick McHardy.

 2) Missed error return check in ipw2100 driver, from Julia Lawall.

 3) PMTU updates in ipv4 were setting the expiry time incorrectly, fix
    from Eric Dumazet.

 4) SFC driver erroneously reversed src and dst when reporting filters
    via ethtool.

 5) Memory leak in CAN protocol and wrong setting of IRQF_SHARED in
    sja1000 can platform driver, from Alexey Khoroshilov and Sven
    Schmitt.

 6) Fix multicast traffic scaling regression in ipv4_dst_destroy, only
    take the lock when we really need to.  From Eric Dumazet.

 7) Fix non-root process spoofing in netlink, from Pablo Neira Ayuso.

 8) CWND reduction in TCP is done incorrectly during non-SACK recovery,
    fix from Yuchung Cheng.

 9) Revert netpoll change, and fix what was actually a driver specific
    problem.  From Amerigo Wang.  This should cure bootup hangs with
    netconsole some people reported.

10) Fix xen-netfront invoking __skb_fill_page_desc() with a NULL page
    pointer.  From Ian Campbell.

11) SIP NAT fix for expectiontation creation, from Pablo Neira Ayuso.

12) __ip_rt_update_pmtu() needs RCU locking, from Eric Dumazet.

13) Fix usbnet deadlock on resume, can't use GFP_KERNEL in this
    situation.  From Oliver Neukum.

14) The davinci ethernet driver triggers an OOPS on removal because it
    frees an MDIO object before unregistering it.  Fix from Bin Liu.
