Building an algorithm optionally into mac80211 seems rather odd.  In
case mac80211 the algorithms should be their own modules and you should
use request_module to make sure at least one is loaded.

We actually do that but people still manage to mess it up because they
don't install the modules properly or whatever.

Or if you
really want to make sure one is alway avaiabable always build the
simplest one directly and unconditionally into mac80211.ko.

That'd be an alternative too, I think we have something like that now. I
don't really like it that much though because for 99% of people it's
just dead code. Anyway, I'll look into Sam's mail and do a new patch
depending on that.
