wifi: Add SAR verification autotests |
|||
Issue descriptionAFAIK, there are no autotests for verifying wifi SAR feature. We need two tests: - switch to tablet/clamshell mode triggers the wifi subsystem to apply the appropriate power table (done today via powerd). This can be done purely in software and can also be a powerd unittest (if not already there). - verify via capturing packets transmitted by the DUT that the tx power of the DUT has changed. This needs a server-side wifi autotest and wificell with pcap and router. Required for <redacted krabbylake> launch.

By "this", I meant the entire end-to-end flow of testing: - use powerd to switch b/w clamshell/tablet. - make the DUT tx via netperf test - have the sniffer capture packets from the DUT. - sniffer parses packets in each case and reports the delta of the RSSI it sees b/w clamshell and tablet. There's a big assumption here the RSSI delta seen by the sniffer will be some function of the actual delta expected by looking at the tx-power table differences.
