Forgive me since i am still missing something ..

Observe that the same threshold used in two different ways:

1) in tx path tx_ring->prunet is to check on when we should _start_ to
prune.
2) on rx path tx_ring->prunet is to check when to _stop_ pruning.

i.e #1 is a preemptive action.

You seem to suggest doing it the way i was it made things worse?

Note that TX interrupts will happen as long as you dont prune some
descriptors (I am assuming this, I havent checked the settings).

cheers,
