bridge dhcp server need restart

[kiokoman]

maybe it is a little bug, this is how to reproduce it:
create a bridge, configure dhcp server and start it,
add an interface on the bridge, the new interface added does not have dhcp server working on it, i need to restart the dhcp server to make it work.
if it is like this, i will suggest to add an automatic restart of dhcp server when you add an interface to the bridge
can someone else check on this? am i the only one with this behavior?
