I'm testing Matt Thomas' experimental DE driver. Well sort of. What would be a good way to stress test this driver? All I've done so far with the driver was a few large sup sessions and running NetScape. Also, how do I check to see if there are any ipintrq drops? -mh On Mon, 3 Jun 1996, Matt Thomas wrote: > > I modified my new/normal if_de.c driver to do something > quite different from most network drivers. > > This driver will defer processing of interrupts to a > netisr routine.
