[Qemu-devel] [PATCH RESEND 4/4] xen nic: check tx queue after connect.

[Gerd Hoffmann]

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.
