From: "Luis R. Rodriguez" <mcg...@suse.com>
The xen-netback driver is used only to provide a backend
interface for the frontend. The link is the only thing we
use, and that is used internally for letting us know when the
xen-netfront is ready, when it switches to XenbusStateConnected.
Note that only when the both the xen-netfront and xen-netback
are both in state XenbusStateConnected will xen-netback allow
userspace on the host (backend) to bring up the interface. Enabling
and disabling the interface will simply enable or disable NAPI
respectively, and that's used for IRQ communication set up with
the xen event channels.
