Not sure why this is a combined cfg/mac patch, there doesn't seem to be
all that much need for that? I'd probably rather see this and patch 6
squashed, but cfg/mac kept separate.

lmt_idx? (also that's only needed in the loop)
bm?

hl?
Could have a bit more evocative names :)
I'd rather see 'i' for some iteration thingie than "lmt_idx" which
means nothing on first reading either, but you start thinking it should
mean something ...

???
That's not how this works upstream.

No need for extra parentheses.

Don't need the n_hw_list check here, the function just does nothing if
it's 0 anyway.
