it's pretty much sure to be the problem, the Geode CPU and vr(4) is not a winning combination for handling high packet-per-second. ping -f to my alix results in about 100% cpu use at 15K PPS. > Is there a way to ignore all packets coming from a certain MAC address > on layer 2? maybe this can be done at the switch. > Is there anyway possible that this is 'legitimate' traffic? damned unlikely.
