Thanks for working on that bug but I have to say that this is
ridiculous. A kernel update gets pushed with a mayor regression that
breaks Wifi and it takes over one month to fix that. The fix for this
issue didnt even land for 19.10 so far. This is just bad.

Title:
  Dell XPS 13 9300 Intel 1650S wifi [34f0:1651] fails to load firmware

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     b81b7bd02eda iwlwifi: remove some outdated iwl22000 configurations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.
