I had not noticed that IPv4 does it, but that is a good point.
We have had a couple of other subsystems with the issue (e.g. MFD),
and have turned around the logic in the end so the user-visible
options are always there and the subsystem core is selected by
all drivers that need it. We could do the same for crypto as below
(untested). I only select CRYPTO from ALGAPI2 there, which may be
wrong if some parts of crypto need the core but do not need algapi,
but it illustrates what we could do.
