Remove all the stupid debug options in your kernel config, and you'll
get >400Mbit on the 2500 :-) I get about 200 on a Firestone with a
2400 (after manually hacking the RGMII clock delays to make it work
at 1000bT).

I'll post a rebase to 4.10 tomorrow. Sadly 4.10 loses another 100Mbit
probably due to kernel bloat.
