> Where do you find the 72ms in the datasheet?

I refer to this commit:
https://github.com/torvalds/linux/commit/1c7412530d5d0e0a0b27f1642f5c13c8b9f36f05
BTW I found that some boards use the RTL8211F-VD PHY,
but I can't find the datasheet.

> In RTL8211F-CG v1.1 I see 10ms and minimum of 30ms, in v1.2 and v1.4

Thanks,
