The bridge interfaces MAC address changes every time you create one, ie
[inchoate 18:11] /usr/src/sys/modules/bridgestp >sudo ifconfig bridge0 create
[inchoate 18:11] /usr/src/sys/modules/bridgestp >sudo ifconfig bridge0
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether e6:91:28:34:39:79
        priority 32768 hellotime 2 fwddelay 15 maxage 20
[inchoate 18:11] /usr/src/sys/modules/bridgestp >sudo ifconfig bridge0 destroy
[inchoate 18:11] /usr/src/sys/modules/bridgestp >sudo ifconfig bridge0 create
[inchoate 18:11] /usr/src/sys/modules/bridgestp >sudo ifconfig bridge0
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether d2:da:21:33:32:df
        priority 32768 hellotime 2 fwddelay 15 maxage 20

so if you reboot then the MAC address will change at each reboot.
