Dear Maintainer,
When running as a Xen HVM guest, after resuming or migrating a couple of times,
the VM will lose its network and the following error appears on the console:
[ 489.940505] xen_netfront: can't alloc rx grant refs
This is fixed by the following upstream commit (in 3.17):
commit a5b5dc3ce4df4f05f4d81c7d3c56a7604b242093
Author: David Vrabel <david.vra...@citrix.com>
Date: Thu Jul 31 17:38:23 2014 +0100
xen-netfront: release per-queue Tx and Rx resource when disconnecting
Since netfront may reconnect to a backend with a different number of
queues, all per-queue Rx and Tx resources (skbs and grant references)
should be freed when disconnecting.
Without this fix, the Tx and Rx grant refs are not released and
netfront will exhaust them after only a few reconnections. netfront
will fail to connect when no free grant references are available.
Since all Rx bufs are freed and reallocated instead of reused this
will add some additional delay to the reconnection but this is
expected to be small compared to the time taken by any backend hotplug
scripts etc.

It would be great if this could be included soon.
Thanks
