>Description:
dhcpcd is too damned noisy with RA announcements from a router.  Multiply the 
active interfaces and you get exponential noise in /var/log/messages as well as 
console notices from syslogd.  Have a minute of my logs with 2 interfaces 
active:

>How-To-Repeat:
This is with dhcpcd=YES in rc.conf at the request of Roy which reduces the 
spamming to this, but it's even worse if you leave sysinstall's 
ifconfig_wm0=dhcp (and ifconfig_bwi0=dhcp) in rc.conf. (you get additional RA 
from unknown with same IP address above which is my router) for 2x the message 
noise.

>Fix:
Punch Roy in the arm until he fixes it and pulls it up to netbsd-6, apparently 
-current is not as noisy, but RA notices aren't
