Description Alexandr Krivulya 2015-10-21 07:00:42 UTC
After upgrade to r289486 ethernet interface on my laptop no longer works and have the same mac-address as a wireless interface. On re0 I see incoming traffic, but all outgoing traffic goes through wlan0 interface.

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

See the thread "Upgrading to r297291 LAGG(4) stops working." -- it might help you out with this issue:

What's your wireless interface (ath, iwn, etc)?
Comment 2 Alexandr Krivulya 2015-10-21 07:44:19 UTC
Yes, I had that issue earlier and change my lagg setup to use wlan's mac-address. But few days ago I figured out that my lagg interface not working via re0 member. I commented out lagg setup in rc.conf and reboot laptop, but when it boots I have re0 interface with mac of wlan interface. 

/etc/rc.conf:

wlans_iwn0="wlan0"
ifconfig_wlan0="WPA country UA"

#ifconfig_re0="ether 68:5d:43:92:3a:88"
#cloned_interfaces="lagg0"
#ifconfig_lagg0="laggproto failover laggport re0 DHCP laggport wlan0"

This situation is reproduced even in a single user mode, when startup scripts is not running yet. My wlan card is iwn0 (Intel Centrino Wireless-N 2230).
Comment 3 Alexandr Krivulya 2015-10-22 14:27:35 UTC
After complete power down laptop and removing battery re0 restored its original mac and network is working now. But it stop working when re0 becomes a lagg member and problem with fake mac-address repeats again until power down.
