It is very curious if we disable all the configs option, a slave
creation raise a BUG (cf. dsa_slave_create). IIUC, booting with NET_DSA
enabled and none of the NET_DSA_TAG* enabled will raise a BUG in the
probe function, right ?

Maybe we should force at least one config when none are set ?

I thought of it earlier. But found the one which i posted better. As we will not
compile DSA stuff now without these tags.

Well, it is the same here, no ? Except, it is up to the user to disable
the option.
