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.

Heh. 228MBit is more reasonable, but I'm getting it up around
235/240MBit at the present moment. I'm hitting queue overruns though,
so I think I've messed something up in the driver, or someone broke
the scheduler in weird/wonderful ways.
I'll let you know when it's at 250MBit again. :)
