After bisect the kernel, the first bad commit is b3bd6416fc77 iwlwifi: assume the driver_data is a trans_cfg, but allow full cfg To avoid conflicts, we have to backport the following commits from mainline kernel b81b7bd02eda iwlwifi: remove some outdated iwl22000 configurations c042f0c77f3d iwlwifi: allocate more receive buffers for HE devices 5661925a9b38 iwlwifi: pcie: rx: use rxq queue_size instead of constant bfc3e9fdbfb8 iwlwifi: 22000: fix some indentation 3681021fc6af iwlwifi: remove IWL_DEVICE_22560/IWL_DEVICE_FAMILY_22560 [Test] Verified on Dell XPS 9300 with Killer AX1650i wifi card and XPS 13 2-1 platform, wifi keeps working after reboot 10 times. [Regression Potential] Medium, the code changes a lot, although the test results are all positive, it's still hard to evaluate the regression potential.
