Under 2.1.130 and some previous kernels, I've been noticing that
ifconfig is reporting almost 100% overrun packets for my slip line.
It is actually connected to a slirp process over a 14.4 modem (okay,
stop giggling now ;-). I've tried reducing the MTU down to 300 bytes,
but that has no effect.
I'm running net-tools 1.47. Here is the ifconfig report:

Here is the contents of /proc/net/dev:

And, just for fun, the output of netstat -ia:
Kernel Interface table

Can anyone suggestion what might be causing this, or how I can find
out more about this problem?
Thanks,
Paul Henning
