Hello Alexander,
The DPAA Ethernet doesn’t work anymore on our FSL P5020/P5040 boards [1] since the RC1 of kernel 5.8 [2].
We bisected last days [3] and found the problematic commit [4]. I was able to revert it [5]. After that the DPAA Ethernet works again. I created a patch for reverting the commit [5]. This patch works and I will use it for the RC2.
Could you please check your commit? [4]
Hi Christian,
Could you please check if the kernel passes CONFIG_TEST_BITMAP self-test?
Thanks!

Hi Alexander,
Thanks for your reply!
I compiled a test kernel with the option "CONFIG_TEST_BITMAP=y"
yesterday. After that Skateman and I booted it and looked for the bitmap
tests with "dmesg | grep -i bitmap".
Results:
FSL P5020:
[ 0.297756] test_bitmap: loaded.
[ 0.298113] test_bitmap: parselist: 14: input is '0-2047:128/256' OK,

Thanks for the test! So it works as expected.
I would suggest to compare what is going on on the device probing
with and without the bisected commit.
There seems to be MAC and PHY mode initialization issue that might
resulted from the bitmap format change.
I put Madalin and Sascha on CC as they have done some works on
this part recently.
Thanks!
