Hello list

I was reviewing the console log [/var/og/messages] and noticed these 
messages.

xlo: promiscuous mode enabled
xlo: promiscuous mode disabled
xlo: promiscuous mode enabled
xlo: promiscuous mode disabled
xlo: promiscuous mode enabled
xlo: promiscuous mode disabled
xlo: promiscuous mode enabled
xlo: promiscuous mode disabled

Now to my knowledge I did nothing to cause this.
xl0 is the interface facing the public internet.

Could this have been a remote attacker?

How to disable xl0 from being able to enter promiscuous mode?
