[Qemu-commits] [COMMIT 3e3cabc] xen nic: check tx queue after connect.

[Anthony Liguori]

From: Gerd Hoffmann <address@hidden>

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.
