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. Cheers, Ben.
