    To generate traffic on a WiFi interface:
    * pick an available (unused) IP on the network

    Set a static arp entry for a fake host on the same network. You may be required to use sudo for the arp command.

    arp -s 10.0.1.199 ab:cd:22:22:22:22

    ! mac is arbitrary
    ! IP should be on same segment

    Send a bunch of traffic out the interface

    cat /dev/random | nc -u 10.0.1.199 22

    ! include port # after ip address

    Control-C to quit

    Interestingly, you can do the same thing on an Aerohive AP with the following commands:

    2.4 GHz radio:
    _test interface wifi0 cont-tx

    5 GHz radio:
    _test interface wifi1 cont-tx
