virtio: virtio_net free transmit skbs in a timer ...
virtio_net currently only frees old transmit skbs just
before queueing new ones. If the queue is full, it then
enables interrupts and waits for notification that more
work has been performed.
However, a side-effect of this scheme is that there are
always xmit skbs left dangling when no new packets are
sent, against the Documentation/networking/driver.txt
guideline:
"... it is not allowed for your TX mitigation scheme
to let TX packets "hang out" in the TX ring unreclaimed
forever if no new TX packets are sent."
Add a timer to ensure that any time we queue new TX
skbs, we will shortly free them again.
This fixes an easily reproduced hang at shutdown where
iptables attempts to unload nf_conntrack and nf_conntrack
waits for an skb it is tracking to be freed, but virtio_net
never frees it.
