Alexander,
I tried todays linux/master on Seagate Dockstar with Marvell 88E1116R
(0x01410e40) and cannot reproduce any regression. I tried booting from
tftp and usb, I also rebooted twice to see if there are any side
effects - nothing - ethernet always comes up as expected.
I am curious, how you determined above commit to be the cause of the
regression you are seeing. Can you bisect, if you didn't already?
