Subject: xen nic: check tx queue after connect.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3e3cabcff9cbddb966833dce432b1409506b4d5b;p=qemu.git

xen nic: check tx queue after connect.

Needed for savevm/loadvm + migration: In that case the queue might
already have packets on (re-)connect.  The guest wouldn't notify us
because notifications are only sent when stuffing a packet into an
empty queue.
