Comment:
{{{
Based on the patch by Georg in http://madwifi.org/ticket/441, I downloaded
the r1457 version and the patch for avoiding duplicate node problems in
input.
}}}
Verified!
I try it with r1467. Without the patch it behaviors as formerly.

And with the nodetable patch (thanks Georg):

So I think the nodetable diff (#441) may be merged into trunk, and resolve
this problem.
There is a similar problem in ap-sta mode, that I can't test now, but this
occurs just if the radio connection losts between the nodes, and the
station reconnects to the ap. I noticed it with station mode. This way the
previous connection stays in the associated_sta file, and as a new
duplication goes into the file.
