Hi all,
The MAC address retrieval logic was broken and when using the PPv2
driver on PPv2.2 engines I ended up using the same mac address on all
ports. This series of patches fixes this, and also tackle a possible bug
when defining the mac address in the device tree.
To fix this in a nice way I ended up using a dedicated function to
handle the mac retrieval logic. This can be hard to backport into stable
kernels. This is why I also made a quick fix which is easy to backport
(patch 1/14), to tackle down the PPv2.2 mac retrieval bug. Let me know
if this approach is the proper way to handle this or if I should do
something else.
Thanks!
Antoine
