> Can we actually introduce NAPI mechanism for cleaning TX ring ??
You really should if you can.
Preferably you should combine it with RX work in a shared NAPI context
(1 TX queue + 1 RX queue per NAPI context, for example), doing the TX
reclaim first in your ->poll() routine, before the RX processing,
because this TX reclaim provides freshly freed up SKBs for RX work
that generates responses (TCP ACKs, etc.)
