Hardware supports different types of MACs eg RPM, SDP, LBK.=20
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 drive=
r
'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 poss=
ible.
