Just do what Sam did in the FreeBSD TDMA code - calculate the actual
beginning of the frame by using the TSF, the size of the last frame,
the rate from the last frame, and call ath_hal_calctxtime() (or the
linux equivalent, obviously.)

For clarification we should find out what the TSF is for 11n
aggregates. Or the math is totally wrong.

Thanks,
