Hardware supports different types of MACs eg RPM, SDP, LBK.
LBK is for internal Tx->Rx HW loopback path. RPM and SDP
MACs support ingress/egress pkt IO on interfaces with different
set of capabilities like interface modes. At the time of netdev driver
registration PF will seek MAC related information from Admin function driver
'drivers/net/ethernet/marvell/octeontx2/af' and sets up ingress/egress
queues etc such that pkt IO on the channels of these different MACs is possible.

Thanks,
Sunil.
