Output after reset is SEL_MIIMAC# used for LED:
When P4MODE[1:0]=11 and DISDUALMII=1, this pin
indicates whether the UTP path or the MII MAC path is
selected. Otherwise, this pin is irrelevant.

Note: When P4MODE[1:0]=11 and DISDUALMII=1,
the RTL8306SD/RTL8306SDM supports UTP/ MAC 4
auto-detection function via the link status of Port4 UTP
and the P4LNKSTA# pin. UTP has higher priority than
MAC mode MII.
LED On: MII MAC path is selected
LED Off: UTP path is selected.
Input upon reset when mode select[4:0]=

This pin is a strapping pin :
DisDSPri. Disable Differentiated Service Priority:

0: Enable DS priority
When in other modes, this pin is a strapping pin:
