You can mark (fwmark) a packet based on the source MAC in 
iptables/ebtables. In the case of bridge, the packet needs to be marked 
by ebtables. tc allows classification by fwmark.
Create a class and assign 3Mbps rate to it. Create a tc filter to send 
all traffic with fwmark 1 to this class. Create a ebtables rule that 
marks all packets coming from MAC address--00:40:33:44:23:44 with fwmark 1.
