[Xen-devel] [PATCH] Fix uncleaned vif backend devices when frontend does not finish initialization properly

[Murillo Bernardes <mfb@xxxxxxxxxx>]

Today if frontend device does not finish initialization the backend vif still
in dom0 forever. The problems are:

- netif_disconnect only clean up devices with connected status. When a device
 has a problem it will not have that status and will not be cleaned up.
- free_netif_callback must be able to unregister devices not completely
 initialized. Today's code test if it has an irq assigned, if not it just
 return. Before a complete initialization netif does not have an irq number.

Both situations occur today when trying to create more than 3 vif in a single
domU.

This patch fix uncleaned vif backend devices when frontend does not finish
initialization properly.

Comments welcome.
