Subject: [next-queue 0/3] i40e: Add an i40e_napi_poll tracepoint

Greetings:

Debugging and tuning the NAPI and i40e NIC parameters can be a bit tricky
as there are many different options to test.

This change adds a tracepoint to i40e_napi_poll which exposes a lot of
helpful debug information for users who'd like to get a better
understanding of how their NIC is performing as they adjust various
parameters and tuning knobs.

Some tweaks to i40e to support this information are made along the way;
including a tweak to i40e_clean_tx_irq (and i40e_clean_xdp_tx_irq, etc)
which returns the actual number of packets processed.

Thanks,
Joe

Joe Damato (3):
  i40e: Store the irq number in i40e_q_vector
  i40e: i40e_clean_tx_irq returns work done
  i40e: Add i40e_napi_poll tracepoint
