But is it calculated only one time after the join? The TSF value in the=
 template is really fast outdated. I think why not let __ieee80211_sta_=
join_ibss() call the set_tsf() callback, so that the TSF is mostly sync=
ed from the beginning on and fine-tuned later by the hardware?

Note: set_tsf() callback is currently broken for newer chipsets. I had =
posted a patch, but this was forgotten to apply. But I can repost it, i=
n the hope that it will be applied now.

Alina
