Good work!
May I suggest adding a "d" to <a b c> where d is flow control - 0 no, 1 yes

Well, I see no reference of the "flow" neither in the include/linux/mii.h
nor in the drivers/net/phy/*. :-/ Thus today there is no such register
bit we can emulate?..

Well, as good as I can recall, flow control(pause) is something that the
PHY negotiates, just like FDX/HDX and should be dealt with in the
adjust_link callback but not many do currently.

If you seach for pause in phy_device.c you will find it.

Ah, pause. Sure, we can emulate that.

Good, looking into phy_device there seems to be 2 pauses:
ADVERTISED_Pause and ADVERTISE_PAUSE_ASYM which
maps to phydev->pause and phydev->asym_pause
so "d" should reflect that or a "e" should be added
for the asym pause.
