Was DPAA functional before commit A?
How about after commit A and before commit B?

The DPAA Ethernet works from  the kernel 5.6-rc4 [1] till the Git kernel from the

Hi,

can you please try to disable the network manager (see [1]), then boot with
the latest kernel, that does not work, and setup the interfaces manually?
