This is awesome, thank you!

(MAC addresses amended manually)

I cannot test if the cards are functional yet - these interfaces are not connected to anything at the moment - but I will let you know if I run into any issues.

Both cards do report 2.5GBASE-T capacity in “ifconfig -m” as expected.

Cheers!
