I'm not convinced that this is a good idea - these frames will still
populate the BSS cache, and it's not really quite well-specified what
happens when you have both [1]
I also don't understand the use case; "might be interested" is ... very
vague.

[1] obviously, today you get both, but an argument could be made for
userspace RX meaning the frame has no action taken in the kernel, like
with action frames.
