Neil just noted the same concern I had -- the asymmetry between
NETDEV_ENSLAVE and NETDEV_BONDING_DESLAVE bothers me a bit.  I also
don't really like the followup patch that uses 'ENSLAVE' in the bridging
code when we typically use that language for bonding only.

What about changing NETDEV_BONDING_DESLAVE to NETDEV_RELEASE and create
NETDEV_JOIN instead of NETDEV_ENSLAVE?  I would prefer that or something
else that might use more generic language that could be applied to all
for stacked interfaces.
