This is outdated.

These two are still valid.

At a minimum, porting the driver from another OS, but AFAIK (I may be wrong)
there will need to be wider changes to the net80211 stack before other 11ac
devices will work. (fewer changes were needed for bwfm where a lot more of
the stack is run on the NIC itself).
