Hello!

BTW trying to strain brains how could driver to use this...

TX irq mitigation is maximally aggressive even without this,
such information is simply useless for mitigation.

Merging index updates? Well, it is too easy to do again
(for drivers using tx spinlock).
Just do not tell driver about new index until at least one of two conditions
happen:
1. >N frames are queued at driver (in hard_start_xmit)
2. <M frames are pushed to device (in tx interrupt).

That's all, you cannot win more using only "more" flag
and not pushing real vector of skbs to hard_start_xmit.
