Well, given the lack of 40Mhz channel support, the best we can do in
theory is 72.2 Mbit/s (20 MHz channel with SGI, see mcsindex.com).
But since we don't support Tx aggregation yet either, protocol overhead
eats up a huge chunk of that.

The peak iwm(4) Tx rate I have measured with tcpbench(1) is about 20 Mbps.
Receive can be faster because 11n APs usually send aggregated frames and
we do support receiving such frames.
