octeontx2-af: Install ucast and bcast pkt forwarding rules
Upon NIXLF_ALLOC install a unicast forwarding rule in NPC MCAM
like below
- Match pkt DMAC with NIXLF attached PF/VF's MAC address.
- Ingress channel
- Action is UCAST
- Forward to PF_FUNC of this NIXLF
And broadcast pkt forwarding rule as
- Match L2B bit in MCAM search key
- Ingress channel
- Action is UCAST, for now, later it will be changed to MCAST.
Only PFs can install this rule
Upon NIXLF_FREE disable all MCAM entries in use by that NIXLF.
