Hi,
What exactly can cause the "Ierrs" on a network interface? It was my
original understanding that they should basically never happen (aside from
hardware failure). I'm currently seeing a lot of them on one of my
interfaces (connected to a cable modem) - can bad packets (framing errors
etc..) cause Ierrs, or is it more likely hardware? The reason I ask is
that the throughput seems a little slow lately, and if replacing the card
would fix the problem - I would. BTW, its an ISA NE2100 clone (Racal) in
my NetBSD-1.4.1/i386 (Pentium/90). Could it be a bounce-buffer
issue? The card uses DMA and I've got 24 Mb of RAM.
Here is the relevant netstat output:
