Just tested Ethernet on a mx6qsabresd board and I see Ethernet is
broken in master. It works fine in 2020.04.

Reverting 4346df3392c0 ("phy: atheros: Make RGMII Tx delays actually
configurable for AR8035") did not help.

git bisect is running into problems:

Error: Cannot open output file
scripts/Makefile.spl:465: recipe for target 'spl/dts/imx6dl-sabresd.dtb' failed
make[1]: *** [spl/dts/imx6dl-sabresd.dtb] Error 1
make[1]: *** Waiting for unfinished jobs....
  UPD     spl/./include/generated/asm-offsets.h
  UPD     spl/./include/generated/generic-asm-offsets.h
Makefile:1940: recipe for target 'spl/u-boot-spl' failed
make: *** [spl/u-boot-spl] Error 2

So not able to run a bit bisect.
