Hi Jonas,
as we found out here
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=845128#63),
FORCE_MASTER was disabled in 2019.01+dfsg-7.
I therefore downloaded u-boot-2020.07+dfsg-1 and did some testing.
System: debian buster
Results are attached.
What i did:
u-boot without FORCE_MASTER

Hello all!
I've made some tests with my Rev C A20 OLinuxino Lime 2 board.
So it uses the RTL8211C Phy.
source used: 2019.01+dfsg-7
The results are somewhat inconclusive i would say.
The board seems to be able to transfer data with TX_DELAY values up to 3.
Retry-counts went up when increasing
