Subject: [Qemu-devel] [PATCH RESEND 4/4] xen nic: check tx queue after connect.
Date: Thu, 11 Jun 2009 11:32:51 +0200	[thread overview]
Message-ID: <1244712771-14432-5-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1244712771-14432-1-git-send-email-kraxel@redhat.com>

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.
