I bet it's like the AR9285 - there's one TX and one RX chain, but two
RX inputs, two LNAs and some controllable bits to determine how the
baseband controls how the LNAs are configured/combined for packet RX.

For clarity (heh), see the diversity combining code in recv.c; it
outlines the various LNA combination modes.
