Tri-Speed Ethernet IP - Link Status up

Hello,

I'm using the Tri-Speed Ethernet IP on an Arria V FPGA.

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_ethernet.pdf

The IP is configured as "PCS Only".

After power-up I expect the Status Register ( address 0x01 - page 94 in the user guide ) to show the value 0x89.

However, what I see is 0x8D - which means the link is up.

And it happens after power-up before I enable anything.

Why does this happen ?
