I found this:

rate_wlan0=( "5.5M" )

which isn't documented in net.wireless, but it doesn't seem to have
any affect. I've tried it on the router and the client which uses
wpa_supplicant. I still see the rate on the client fluctuate all the
way up to 54 Mb/s in the output from iwconfig. The router's rate is
always reported as 0 kb/s.
