octeontx2-af: NPC: Clear Unicast rule on nixlf detach
The AF driver assigns reserved MCAM entries (for unicast, broadcast,
etc.) based on the NIXLF number. When a NIXLF is detached, these entries
are disabled.
For example,
PF NIXLF
--------------------
PF0 0
SDP-VF0 1
If the user unbinds both PF0 and SDP-VF0 interfaces and then binds them in
reverse order
PF NIXLF
---------------------
SDP-VF0 0
PF0 1
In this scenario, the PF0 unicast entry is getting corrupted because
the MCAM entry contains stale data (SDP-VF0 ucast data)
This patch resolves the issue by clearing the unicast MCAM entry during
NIXLF detach
