FSL P5020/P5040: DPAA Ethernet issue with the latest Git kernel
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?
