I happened to be looking in net80211/ieee80211_var.h and examined the
macros IEEE80211_MS_TO_TU and IEEE80211_TU_TO_MS. The conversions seem
backward to me. The macros are:



#define IEEE80211_MS_TO_TU(x) (((x) * 1000) / 1024)

#define IEEE80211_TU_TO_MS(x) (((x) * 1024) / 1000)



If I take the values:

1 second = 1000 milliseconds (ms) = 1024 timer units (tu)

Please reread 802.11-1999, page 6, 3.45:
one tu is 1024us
