Let me rephrase.=C2=A0

I would like to modernize the wifi stack so that ioctls are not = used anymore in ifconfig scan operation, for example. I would like to use n= etlink instead.

It depends on from which side of view.
Let's limit "can we borrow any code without violating its license?= "
here.

>From the point of view from GPL'ed software, BSD license is
100% compatible.

OTOH, from the point of view from BSD licensed software, GPL is
incompatible (because BSD license does not force licensees to make
their modified/added codes to be GPL'ed).

And FreeBSD has, for example, CDDL'ed codes like OpenZFS in tree,
without any action to delete them, unlile GPL'ed ones.

This is, (my understanding is) because CDDL is considered as
BSD-compatible license. There are more, for example, MIT license and so
on.

So any of BSD-compatible license is/are included in multiple licenses
of the codes, FreeBSD can introduce it in tree.

This is my guess.
