Subject: IPX socket shutdown() is not implemented

Hi, as suggested by Alan [1], I'm spreading this in the list hoping
that someone with a better understanding can help solving this issue.
>From bugzilla [2]:

With no support to shutdown a parallel (other thread) poll call is not
waken up so applications hang indefinitely while waiting for an
answer.

Still in the latest development version as seen in:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/net/ipx/af_ipx.c?id=refs/tags/v3.13-rc5#n1966

The problem was found while debugging a windows game through wine, the
game is Dune 2000 and the sister bug is
http://bugs.winehq.org/show_bug.cgi?id=6941

I understand that IPX is somewhat defunct nowadays but at the same
time by looking in the inet_shutdown function I believe it can be
simple to implement the same for IPX.
