Hello everyone, I have several systems with three integrated Intel 82559 (I *think*). Does someone know if these boards support hardware interrupt mitigation?
82558/9 hardware does, sort of. But the e100 driver doesn't use it because it uses NAPI to minimize rx & tx interrupts.
I.e. is it possible to configure them to raise an IRQ only if their hardware buffer is full OR if some given time (say 1 ms) has passed and packets are available in their hardware buffer. I've been using the eepro100 driver up to now, but I'm about to try the e100 driver. Would I have to use NAPI? Or is this an orthogonal feature?
Use NAPI. The e100 driver has been NAPI-only for a while. -- James Chapman Katalix Systems Ltd http://www.katalix.com Catalysts for your Embedded Linux software development - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
