So as we discussed, I think you should add a note here that the flag
only works for some interface types, and prohibit setting the flag when
unsupported ones are supported. Then you can also remove the message and
just put in a WARN_ON(1) or something since you can't really get to that
code path.

IMHO that's a reasonable trade-off between generalisation and not doing
all the work now especially since you can't validate it over Intel hw
for other interface types - if anyone else needs/wants the flag then
they can add those interface types and change the conditions.
