I recently bought one in an attempt to get qca8k working on it.
Unfortunately the bootloader disables all ports except WAN and the
driver has a hack that disables MDIO 0-3, which qca8k seems to need. I
tried removing it but then mdiobus_alloc fails with error code -5.

qca8k only manages to bring up port 5 (WAN).
