If a receive frame error line status caution level has been occurred, the status of each
station can be checked by PORT2 error frame reception detection status (1) (SW0150
to SW0157).
Depending on the timing of the link refresh, the update of PORT2 error frame
reception detection status (1) (SW0150 to SW0157) may be offset by one sequence
