Ok, so it's similar to wlan where we need some extra configuration before we can use it.

If this is the case the code is broken. It should just work with the vendor dtb and GENERIC. We already have to handle the We already have to handle this in other parts of the code by having the dependent drivers on an earlier pass than later drivers. I also don't see any documentation. I can see the bgx driver, bit there doesn't seem to be a manual page. root@cavium:~ # man bgx No manual entry for bgx Andrew
