Hi, folks!

I've got an unusual problem/behavior, when configuring a bridge 
interface with tap interface members (the bridge interface disappears 
after the "ifconfig bridge0 addm tap0" command)...
see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271869

Has anyone encountered a similar problem and knows how to fix that?
