Build Update for igsilya/ovs
-------------------------------------

Build: #622
Status: Broken

Duration: 47 mins and 11 secs
Commit: 3ca5753 (tmp-master)
Author: Ilya Maximets
Message: netdev-afxdp: Fix transmission freeze in native mode without zerocopy.

Kernel uses 'xsk_generic_xmit()' for all modes where zerocopy is
not enabled:

   net/xdp/xsk.c
   433  static int __xsk_sendmsg(struct sock *sk)
   434  {
            ...
   442      return xs->zc ? xsk_zc_xmit(xs) : xsk_generic_xmit(sk);
   443  }

This means we need to kick Tx with sendmsg() for each 16-pack of
packets in a simple native mode too, otherwise packets will never
be sent.
