<div class='commit-subject'>Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net</div><div class='commit-msg'>Pull networking fixes from David Miller:

 1) We have to be careful to not try and place a checksum after the end
    of a rawv6 packet, fix from Dave Jones with help from Hannes
    Frederic Sowa.

 2) Missing memory barriers in tcp_tasklet_func() lead to crashes, from
    Eric Dumazet.

 3) Several bug fixes for the new XDP support in virtio_net, from Jason
    Wang.

 4) Increase headroom in RX skbs in be2net driver to accomodate
    encapsulations such as geneve. From Kalesh A P.

 5) Fix SKB frag unmapping on TX in mvpp2, from Thomas Petazzoni.

 6) Pre-pulling UDP headers created a regression in RECVORIGDSTADDR
    socket option support, from Willem de Bruijn.

 7) UID based routing added a potential OOPS in ip_do_redirect() when we
    see an SKB without a socket attached. We just need it for the
    network namespace which we can get from skb-&gt;dev instead. Fix from
    Lorenzo Colitti.
