+1, we should move people away from brtcl. there is enough confusion
among users looking at bridge attributes.,

ip -d link show
bridge -d link show
brctl

Adding a 4th one  to the list is not going to ease the confusion. We
should try to make the 'ip -d link show and bridge -d link show'
outputs better. Any suggestions there from people will be useful.
