[Olsr-dev] Feedback on current OL

[David Murray]

Hi guys, just a bit of feedback on the latest development branch found 
here [1]. I have had it running in my test setup (8 dual radio ALIX 
nodes) for about 3-4 days. It seems to be working great, however, one 
problem I have found is with the the metric.

Currently, I have a 100mbit Ethernet link that is being given a metric 
of ~1.150. Iperf shows that this link provides ~100 mbit which means 
that there is nothing physically wrong with the link. To investigate a 
little further I pulled up wireshark and took a look at the OLSR hellos.

The wireshark output was showing some UDP checksum errors "maybe caused 
by UDP checkum offload" on some olsr hello packets. Perhaps if anyone 
else is using this branch they could confirm whether they are also 
getting the errors or if it is something specific with my equipment.

Thanks
Dave
