In fact the ping was "ping -s 1472 -c 1000 -i 0.002", that's more than
12Mbit/s pushed into the link. Sorry, I shouldn't call it "ordinary ping".
I didn't say it was perfect, but it couldn't have been completely inaccurate,
because I found the athctrl value for 11a mode and Madwifi value for 11g mode
that way.

OK, I will prepare a revised patch series. However I need to fix the usec to
clock conversion in Ath5k before (currently it's correct for 802.11a only).
