Subject: Try to fill route cache

Hi,

I try to test a programm, that manages ca. 120000 connections at the
same time.

Now I want to test it with a full route cache. I can only test it from
some Test-PC's.
So the route cache ist nearly empty all the time.

I tried to fill the route cache with pktgen amongst others with the
appended configuration, but my route cache is always nearly empty.
In my log this error appears:  "eth0: too many iterations (6) in
nv_nic_irq."

I use Kernel "2.6.16.13-4-smp".

Where is the problem ?

Thanks in advance

Markus Wenke
