eth: fbnic: Add L2 address programming

Program the Rx TCAM to control L2 forwarding. Since we are in full
control of the NIC we need to make sure we include BMC forwarding
in the rules. When host is not present BMC will program the TCAM
to get onto the network but once we take ownership it's up to
Linux driver to make sure BMC L2 addresses are handled correctly.
