Hi Gianluca,

You probably have the 'bridge' command available in there, it's the 
iproute2 version of brctl tool. Just like we had ifconfig->ip, we are 
having brctl->{bridge,ip}..

Note that 'bridge' is for bridge-specific stuff, like:

$ bridge link help
Usage: bridge link set dev DEV [ cost COST ] [ priority PRIO ] [ state 
STATE ]
                                [ guard {on | off} ]
                                [ hairpin {on | off} ]
                                [ fastleave {on | off} ]
                                [ root_block {on | off} ]
                                [ hwmode {vepa | veb} ]
        bridge link show [dev DEV]

while you may create the bridge itself via ip command.
