 # brctl addbr "bridgename"
 # brctl addif bridgename device

See MAC table

 # brctl showmacs

Interface must be UP

 # ifconfig <bridgename> up
 # vconfig add <bridgename> [vlanid]

configuration above should work with applying this (bridge.diff) patch to your linux kernel. Otherwise you need to do this like this

# ifconfig ethX up
# ifconfig ethY up
# vconfig add ethX [vlanid]
# vconfig add ethY [vlanid]
# brctl addbr "bridgename"
# brctl addif <bridgename> ethX.vlanID
# brctl addif <bridgename> ethY.vlanID
