Commit Message

Geetha sowjanya July 12, 2024, 5:55 p.m. UTC
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. This patch add representors for SDP MAC.
