>Description:
when using freebsd in dhcp-pd configuration, rtadvd logs that RA are received on an interface that isn't configured. This is expected behaviour and the logs should not log for this situation.
>How-To-Repeat:
configure freebsd for DHCP-PD, startup rtadvd for your inside interface with no confiuration for your outside interface.
>Fix:
use the sysctl RFC6204W3 to decide to log these messages or not.
