Have you checked the rst output for this? Seems likely that's not going
to be great with that formatting, but I haven't checked.

"@hw_chans" doesn't make sense here, this is nl80211, it should refer to
some attribute
but why didn't you just _say_ in the patch 2 discussion that it's used
here ...

Almost all these attributes duplicate - including their docs -
attributes from enum nl80211_if_combination_attrs. Is it really worth
doing that, rather than adding NL80211_IFACE_COMB_HW_IDX and documenting
the different uses of the attribute set?
