thx for the fix, as daniel already checked it on mt7986/bpi-r3 i tested bpi-r2/mt7623

but unfortunately it does not fix issue on bpi-r2 where the gmac0/mt7530 part is affected.

maybe it needs a special handling like you do for mt7621? maybe it is because the trgmii mode used on this path?

Could you please test if making it use the MT7621 codepath brings back 
performance? I don't have any MT7623 hardware for testing right now.

used the CONFIG_MACH_MT7623 (which is set in my config) boots up fine, but did not fix the 622Mbit-tx-issue

and i'm not sure i have tested it before...all ports of mt7531 are affected, not only wan (i remembered you asked for this)

Does the MAC that's connected to the switch use flow control? Can you 
test if changing that makes a difference?

it does use flow control/pause on mac and switch-port, disabled it, but it does not change anything (still ~620Mbit on tx)
