Candela LANforge New Release 5.4.6

Release 5.5.1  

• TR398v4: Update pass/fail for the Rx Sensitivity test to match the updated TR398i3-c1 document. The original TR398i3 document had incorrect pass/fail in the test specification. Please ensure that the pass/fail configuration in the Rx Sensitivity test in LANforge TR398 are set to the 'Default' values after upgrading, as the old defaults have now changed. Internal fixup to work around the test-spec problem have been removed.
• TR398v4: Support running most tests at different spatial stream count and different packet sizes to allow users to customize to test beyond the official TR398 specification.
• TR398v4: Initial support for eMLSR test using 5Ghz + 2.4GHz bands (as well as the previously supported 5GHz + 6GHz bands test).
• TR398v4: Add MLO STR (MLMR) test case support.
• WebGUI now supports Dataplane, Hunt, Rate vs Range and some other Chamber-View test suites.
• Support 6.15 kernel for latest drivers and bug fixes and tri-band MLO-STR MLMR support when using the Mediatek 7996 radio.
• Dataplane: Optimize (re)configuring wifi configuration when running with outter loop being Attenuation.
• Dataplane: Ongoing improvements and optimizations to work with IOT devices and android devices running iperf.
• AP-Auto: Improve tri-band converage and general bug fixes and improvements.
• AP-Auto: Improve hunt and related test options and performance.
• Audio Quality: Improve report, allow configuring internal delay to make latency report more accurate.
• Intel be200: Support 6Ghz puncturing feature in US and CA regulatory domain.
• Mediatek 7996: Initial support for 34 virtual stations per radio per band is available in 6.15.6+ kernels.
• Fix IP checksum offload in mtk7996 driver for improved upload throughput.
• Cell-Emulator: Add test case for Ethernet to 4g/5g cellular backhaul failover. This utilizes LANforge integration with ALifecom LTE/5g cell emulator, plus other equipment to make a complete and self-contained cellular backhual testbed.
• Windows: Support setting QoS/ToS in layer-3 TCP and UDP connections. Windows makes this harder than expected, but now it works!
• Interop: Add support for Windows-ARM machines (Surface)
• Interop: Add support for iPad
• Interop: Improve Android app logic to re-connect to the LANforge manager when wifi connection is lost.
• LANforge-Manager: Add 'Aux-Mgt-Lite' feature to more easily manage Interop testbeds over LANforge manager's data generating interfaces (AP, Ethernet, etc). This makes it easier to manage complex Interop testbeds.
• Provide RPI5 kernel patched with Candela patches for extra stats and features.
• Support forceably disabling 40 and/or 80MHz bandwidths when STAs associate to APs supportion 80+MHz. This is probably against the wifi specification, but feature was requested and it may be useful for certain tests.
•  

  Significant Bug Fixes

• TR398v4: Fix disabling puncturing at end of the test (when using helper script. As work-around, helper script can use 'puncturing' as well as 'puncture' for the key.
•  

  Known Limitations

• Multiple stations on the 'combined' phy on mtk7996 radios has stability problems, especially after many admin up and down. These problems are not seen when using the single-phy radios. There was no combined phy at all in earlier releases, so while we do want to fix this, it is not really a regression.
• Virtual stations (more than one station per radio) have problems when connecting to AP that does OFDMA. Work-arounds include disabling OFDMA on the AP or forcing the virtual stations to support only VHT instead of AX. This is probably a hardware limitation and is unlikely to be fixed with currently available radios.
