if_bridge broadcast

[Dag-Erling Smørgrav]

I have a box that amongst other tasks serves as a printer server and a
wlan bridge.  The wired and wireless interfaces are members of the
bridge, and are unconfigured (except for ssid etc. on the wireless
interface).  The bridge itself has an IP address, is subject to packet
filtering etc.

There is a hitch, though: the bridge does not have the IFF_BROADCAST
flag set, so CUPS browsing (which is based on sending printer status
announcements to the broadcast address) doesn't work.

Is there any reason why a bridge can't have the IFF_BROADCAST set - if
not unconditionally, then at least when all its members have it?
