This adds a few utilities for setting up an FT environment. All the roaming tests basically copy/paste the same code for setting up the hostapd instances and this can cause problems if not done correctly. set_address() sets the MAC address on the device, and restarts hostapd group_neighbors() takes a list of HostapdCLI objects and makes each a neighbor to the others. The neighbor report element requires the operating class which isn't advertised by hostapd. For this we assume operating class 81 but this can be set explicitly if it differs. Currently no roaming tests use 5/6GHz frequencies, and just in case an exception will be thrown if the channel is greater than 14 and the op_class didn't change. --- autotests/util/hostapd.py | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+)
