Arria10 TSE w/ option "1000Base-X PCS/PMA" is accessible from CPU MDIO Bus ?

Hello TSE expert,

We use Arria10 TSE w/ "1000Base-X PCS w/ PMA" variation. the TSE exports MDC/MDIO/MD_EN line.

My ques : I understand if TSE connect to an external PHY device, then connect these TSE MDIO pin to the external PHY device mdio i/f, so Host Driver（Linux） can access to probe PHY device registers by using MDIO interace.

Now in our design, we initiatiate TSE IP with embedded PCS/PMA <-to-> external SFP, does the embedded PCS module has the MDIO interface , thus for Host Driver is able to probe it, to make the mdio operation work as expert from CPU ethernet framework view ?

If yes, what'is the procedure to config TSE PCS config to make its MDIO working ? Thanks a lot
