Subject: 82557/8/9 Ethernet Pro 100 interrupt mitigation support

Hello everyone,

I have several systems with three integrated Intel 82559 (I *think*).

Does someone know if these boards support hardware interrupt mitigation? 
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?

Regards.
