# This test run is meant to test AP hopping.  This is a fairly
# simple test and is very "kind" to the DUT, in the sense that
# when we do an AP deconfig, it sends out a DEAUTH, so the DUT
# should be immediately aware that it is time to scan for a new
# AP.  This should be a best-case roaming test.  This test differs
# from regular "ChannelHop" in that the BSSID of the AP is changed.
# This means that even with fullmac drivers that may change
# channels without a lot of upstream notification, this test should
# definitely cause upstream notification to the supplicant and by
# extension, flimflam.
