For BF with old FW which doesn't expose the E-Switch Manager vport ID,
E-Switch Manager port matching works correctly only when BF is in
embedded CPU mode.
This patch adds the limitation description.

When meter is used by E-Switch Manager port, there's an error that
cannot get correct port ID.
This patch fixes this by using specific parsing process to get port
ID for E-Switch Manager.
