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'

FSL P5040:

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!

Hi All,

The issue still exists [1] so we still need the dpaa patch [2]. Could 
you please check the problematic commit [3]?

Thanks,
Christian
