Stratix 10 HPS to 25G ethernet interface
I believe Stratix 10 HPS is capable of 10/100/1000 Mb, not 10G/25G.

You may have seen this already, but there's a 25G reference design, but it's connected to the fabric.

we plan to use the 25G Ethernet Stratix 10 IP with MAC+PCS+PMA. We are using this to conenct to a gransmaster cllock for PTP time sync. We have enabled IEEE 1588 in the IP core. also have enabled Enable 10G/25G dynamic rate switching.
We want to know,
- How to controll the switch between 10G and 25G.
- How to interface the 25G IP to the Stratix 10 HPS.
We do not need 25G throughput, just need the phyical interface for IEEE 1588 time sync messaging.
