Public bug reported:
[Impact]
Some improvement are made to qat which makes it
more resilient and able to handle reset in a
better way.
There is an upstream patch set that improve this
but it's applied to linux-next and scheduled for 6.9.
We should apply the patch set to the Noble 6.8 kernel,
so we experience less issues with qat and be more maintainable.
[Test case]
Use the added mechanism to inject errors and rmmod/modprobe the module
to verify that qat recover and log issues properly.
[Fix]
Apply the following commits (from linux-next):
