I fail to see how the TSF could be related to an ever reconnecting
station. Can you elaborate on what happens?

I was under the impression that the firmware would handle TSF stuff.
Also the "IBSS leader" is a new thing to me. I remember from the specs
that the device should accept the TSF from _any_ beacon. Not just a
"leader". Am I mislead? :)

I also fail to see how we could _ever_ set the TSF to something remotely
correct from the driver because of the FIFO delay.

I cannot find this patch in wireless-testing and I don't
have a copy of wireless-2.6 here. Can you send me the patch, or
explain what it does?
