Our hardware has multiple MACs RPM, SDP and LBK.
Also, hardware doesn't have an internal switch.
LBK is a loopback mac which punts egress pkts back to ingress pipeline.
RPM and SDP MACs are the ones which does IO to outside of system each suppo=
rting different modes ranging from 10/100/1000BaseX to 100Gbps KR modes.
