So no notifications at all? Mhh .. I guess its OK for now, this stuff
needs to be fixed to notify once for all changes anyway.
I'll resend the following patch with the new ifgroup patches. The
current changes: changes are now atomic and a notification will be send
later at the end of the function. If an address was changed, a
notification will be send and after that another which is always sent
when anyi modification happened.
This patch may not be complete.
