Well, that showed one of these every three seconds:

Further investigation shows that the source MAC address belongs to a wired
port on the wireless access point. When this laptop is on a wire the traffic
doesn't occur, but when on wireless it is there. Any suggestions as to what
it is and maybe how to stop it. The AP is a Netgear WPN824v2.
