[Xen-devel] [PATCH] Fix qemu-xen with PCI passthrough.

[konrad@xxxxxxxxxx]

Hey Anthony and Stefano,

This patch was posted in the past (see
http://lists.xen.org/archives/html/xen-devel/2013-07/msg00008.html)
and Stefano said: ""It looks OK to me, I'll have to trust you to have
tested this patch properly too.".

I don't recall if Zhenzhong did, but I just did with Xen-unstable
and the latest of qemu-xen. Without this patch, this loop

while (true)
do
 rmmod igbvf
 killall dhclient
 modprobe igbvf
 dhclient eth1
done

ends up shorlty exhausting the list of PIRQs and the driver cannot load
anymore. With this patch the loop continues on.

This has been tested with an 82576 VF.

Please pull!
