Hi,

If the device EEPROM states that it's a 2x2/3x3 device, it'll TX on
two/three streams.

If it's something like an AR9281 where it's physically a 1T2R stream
device, that's what it'll transmit/receive on by default.

If it's something like an AR9285 where it's physically a 1T1R stream
device with antenna diversity, that's also what you get.

If the device EEPROM lies though, well, that's a problem. :-)
