- bool "Use Rx Polling (NAPI)"
- depends on VIA_RHINE
- help
- NAPI is a new driver API designed to reduce CPU and interrupt load
- when the driver is receiving lots of packets from the card.
-
- If your estimated Rx load is 10kpps or more, or if the card will be
- deployed on potentially unfriendly networks (e.g. in a firewall),
- then say Y here.
