[Olsr-dev] another

[Peter Tarjan]

Hi,

I think I've found another little thing to fix in olsrd-0-5-6-r4 when
tested with two machines having two olsr network interfaces each.
In function check_link_status(...) an UNSPEC_LINK neighbor information
can override an ASYM_LINK, just their order in the HELLOLQ packet
matters.

Please consider applying my patch to eliminate this problem:
