The prerequisite for MLO support in cfg80211/mac80211 is that all the links
participating in MLO must be from the same wiphy/ieee80211_hw. To meet this
expectation, some drivers may need to group multiple discrete hardware each
acting as a link in MLO under single wiphy. So it required to have some
sort of mapping while describing interface combination capabilities for
each of the underlying physical hardware. This patch set tries to add an
infrastructure to advertise underlying hw specific capabilities like
channel and interface combinations.

Some of the todos

 - More than one concurrent monitor mode support each operating on
   different channels under one ieee80211_hw
 - Mechanism for each underlying radio specific configurations like
   txpower, channel, etc.
