I did some test, and the value returned by ath5k_hw_get_slot_time was always
9, even when connected to 802.11b-only AP. I didn't try the turbo mode,
though. Unfortunately I don't know how to calculate ACK timeouts for
a different slot time - the formula I used is the only one in both Madwifi's
and FreeBSD's athctrl.
Also the calculation of initial slot time is not expained anywhere, there are
only some magic values in initvals.c.
