I do _not_ run powerd (/etc/defaults/rc.conf checked, /etc/rc.conf/checked,
pgrep powerd done)

I got rid of the

     power_profile: changed to 'performance'

in /var/log/messages by commenting out the entry:

     # Switch power profiles when the AC line state changes.
     notify 10 {
         ...
     };

of /etc/devd.conf

the packet loss (ping -s 1450 -c 200 on the test station) remains at 3.0%

stuck beacon messages continue to flow
