Howdy,

Just playing with this a bit. A couple of questions.

I've gotten this to compile on Sol 10 on sparc as an upgrade on Solaris
9 and a fresh spanking new Solaris 10 x86 05/07 and Solaris 10 x86 01/06.

In each case if do an brctl addif mybridge <primary interface> I get the 
following immediately from the command line:

Bridge bridge is /devices/pseudo/bridge at 0:1
brctl: sending DLPI message: 00 00 00 0B 00 00 00 00

brctl

and behind the scenes a ton of kern warn and notice items such as
syslog race conditions with WARNINGs and the following type of output in
messages

until the system panics and reboots.

Any thoughts.....

Also you reference that it doesn't work yet with IPFilter. Does this
mean that having IP filter running AT ALL is an issue or that the bridge
cannot span through IP filter or be otherwise managed by IP filter.

Thanks

[about a panic]

We need to see a less corrupted copy of the panic messages.  Or start up
mdb(1) on the crash dump files and type $c and send that output for
starters.

You may have hit a bug in the debug message code; you could try setting
bridge_debug to 0 or 1 instead of 2.  I'm pretty sure the debug level 2
code will panic on SPARC if it receives an unaligned packet, for example.

bridge and IPFilter co-exist just fine, but IPFilter doesn't see or filter
packets as they go through the bridge; IPFilter only filters packets as they
enter or leave the IP stack.  Someday we'd like to have IPFilter acting on
the packets as they go through the bridge.
