It seems wasteful to add per-packet overhead for tx timeouts, which
should be an exception. Do drivers really care about the exact
timeout value? Compared to a packet transmission time its incredibly
long anyways ..

I agree. Doing a mod_timer or hrtimer_forward to push forward may add to the
complexity depending on how often TX happens.

Are the drivers really worried about exact timeouts here?

Just guessing, but I don't think they are, after all timers can be late.

Can we use rounding for the timers that are more than a second, at least?

Also sounds reasonable.
