== Bionic Justification ==
This is a backport request from Netronome for Ubuntu 18.04 LTS.

Description: Previously it was possible to interrupt processing stats 
updates because they were handled in a work queue. Interrupting the stats 
updates could lead to a situation where we backup the control message queue. 
This patch moves the stats update processing out of the work queue to be 
processed as soon as hardware sends a request.

The following fix for the above has been accepted into upstream for v4.16. 

== Fix ==
01c15e93a78c ("nfp: flower: prioritize stats updates")

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
