Bug description:
[Impact]
It dumps some debug messages while loading iwlwifi firmware every time after
booted up and finally got below errors
[ 5.632845] iwlwifi 0000:00:14.3: Failed to start RT ucode: -110
[ 5.632849] iwlwifi 0000:00:14.3: Firmware not running - cannot dump
error
[ 5.645491] iwlwifi 0000:00:14.3: Failed to run INIT ucode: -110
[Fix]
It looks like it fails to load the firmware since mainline v5.4 kernel, and
got fixed at v5.6-rc1. 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b81b7bd02eda iwlwifi: remove some outdated iwl22000 configurations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.
