not exactly - it was allocated in CPSW .probe() manually, 
in without this re-work it has to be allocated in NTCP the
same way - manually. So, checks we are discussing here will be still
present, but they will need to be done in CPSW/NETCP drivers -
just one level up and duplicated in both these drivers.
