dhcpcd-discuss

Hi Roy!

I'm trying dhcpcd 8.0.6 on my device to check if it can pass Bonjour
Conformance Test and to decide if upgrade or not.
However *8.x.x causes lot of issue when running IPV4 Link Local test**.*
With 6.x.x and 7.x.x the situation was ok.

This is the log (very verbose with DD options) of Bonjour Conformance Test
1.5.0 with dhcpcd 8.0.6 executed with* "dhcpcd -q -i eth0"*


*sudo ../BonjourConformanceTest -I en0 -DD -F results.txt*
