You'll have to ask Felix and others, but I think they're more generic
APIs to support things like AR9285 (and the relevant AR9300/AR9400
series NICs) which implement 1x1 but have "classic" style antenna
diversity.

Also, as I've discovered, you _can_ glue an antenna switch onto the
side of a MIMO NIC. Eg, I have an AR9220 based NIC (2x2:2) which has
three antennas, both the second and third are connected to chain 1 via
an antenna switch.
