Title:
  Kernel crash during Mellanox performance testing

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  * When performance testing using Mellanox driver, an early decrement
  within an if condition rather than as a result of an if condition is
  causing null pointer crashes.

  [Fix]

  * Clean cherry-pick from upstream 
(https://lore.kernel.org/netdev/20220503044209.622171-10-sae...@nvidia.com/)
  * Change landed v5.19 upstream, Kinetic onward not affected

  [Test Case]

  * Compile test
  * Boot test
  * Performance test

  [Where things could go wrong]

  * Regression risk is low, localized fix, purely fixes incorrect logic
