mlxsw: reg: Add Port Module To local DataBase Register
The PMTDB register allows to query the possible module<->local port mapping than can be used in PMLP. It does not represent the actual/current mapping of the local to module. Actual mapping is only defined by PMLP. Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
