[PATCH v2 2/4] tools/hotplug: combine add/online and remove/offline in vif-bridge...

[Paul Durrant <paul@xxxxxxx>]

From: Paul Durrant <pdurrant@xxxxxxxxxx>

... as they are in vif-route.

The script is invoked with online/offline for vifs and add/remove for taps.
The operations that are necessary, however, are the same in both cases. This
patch therefore combines the cases.

The open-coded bridge removal code is also replaced with call to
remove_from_bridge().
