5.2 Merge Window second pull request

Browse Source 
This is being sent to get a fix for the gcc 9.1 build warnings, and I've
 also pulled in some bug fix patches that were posted in the last two
 weeks.
 
 - Avoid the gcc 9.1 warning about overflowing a union member
 
 - Fix the wrong callback type for a single response netlink to doit
 
 - Bug fixes from more usage of the mlx5 devx interface
