Indeed, either of those will work.

Yeah, I saw that discussion. I think it's fine, it's just something we
need to be aware of. In fact, I Joe had a patch (that seems to have
gotten lost?) to make DECLARE_MAC_BUF() declare a structure with the u8
pointer in it instead to get type checking for the args, which would
make our code there not even compile, and imho rightfully so. I'll send
in a patch to fix this (via John) and Joe can resend his patch to get
typechecking there.
