You're trying to set a multicast address, that's not allowed. 

# ifconfig bridge0 static vtnet1 11:22:33:44:55:66
ifconfig: BRDGSADDR vtnet1: Invalid argument
# ifconfig bridge0 static vtnet1 10:22:33:44:55:66
# ifconfig bridge0 addr
10:22:33:44:55:66 Vlan1 vtnet1 0 flags=1<STATIC>

Quoting https://en.wikipedia.org/wiki/Multicast:
"Ethernet frames with a value of 1 in the least-significant bit of the first
octet of the destination address are treated as multicast frames ..."
