I sent out a v5. This should fix the issues you reported. I tested extensively link speeds and resume/suspend using a laptop and a loop-back cable between and AX88279 and an AX88179B using netns. I tested around 20 suspend/resume cycles and found no issues even with different speeds with the fixes in v5. Cheers, Birger
