[dpdk-dev] vhost: add missing build dependency on librte_net

  Commit d0cf91303d73 added dependency on librte_net headers to vhost
but did not add this to the Makefile, which makes builds
non-deterministic. Curiously it is non-parallel build that is
consistently broken by this missing dependency, usually it's the other
way around, but trying to build without -j(n) fails with:

	dpdk/lib/librte_vhost/vhost_rxtx.c:41:20:
	fatal error: rte_ip.h: No such file or directory

Fixes: d0cf91303d73 ("vhost: add Tx offload capabilities")

Yeah, I have confirmed it; I was wondering why I didn't meet such build
error.

Thanks.

BTW, please cc me for virtio/vhost patches next time, otherwise, it's
easily got overlooked: too many emails.

Hmm, I thought I did. Looking more carefully now, I mixed up the patch 
author (who was CC'd) with you:

commit d0cf91303d731997945420832ee245b21f292e19
Author: Jijiang Liu <jijiang.liu@intel.com>

I hate it when people call me Paul (commonly happens) just because it 
vaguely resembles my name, so I really should do better than this. 
Apologies, I'll pay closer attention in the future.

I didn't see the author was cc'ed from my email client:

    Date: Thu, 18 Feb 2016 11:47:43 +0200

Hmm... I didn't call you that, right?

Indeed :)

Never mind, it's not a big deal. Emails with me CC'ed are highlighted
in my mutt email client, therefore, it's unlikely I will miss them.

Hmm, indeed. But this is what git told me (happened to have the whole 
thing in scrollback buffer):

So where do the CC's vanish?

No idea. I also have met this issue __many__ times before: I made a
group reply, with lots of people CC'ed, later I then received a copy
(from the mailing list) with all cc list being vanished -- only
dev@dpdk.org is left. However, I found the CC list was there while
I checked the sent box.

I was firstly thinking it might be an issue of my email client. However,
I also found same phenomenon from other's reply. Just not sure whether
they removed the cc list on purpose or not, though. IIRC, this also
happened to Bruce (CC'ed).

Anyway, since you have met similar issue just now, I guess it's time to 
shout out and let this issue get noticed, or fixed if there is indeed
an issue. The mailing list is with high chance being the culprit, IMO.
Hence, Thomas is CC'ed.

BTW, I have never meet this issue with git send-email.

Yes this is due to the "no duplicates" option of mailman:
	https://bugs.launchpad.net/mailman/+bug/1216960

I am checking how to disable it.
