[PATCH v2 0/7] features provisioning fixes and mlx5_vdpa support

From: Si-Wei Liu
Date: Tue Jan 31 2023 - 18:23:41 EST


This patchset is pre-requisite to export and provision device
config attributes and features for vdpa live migration, in a way
backward and forward compatibility can be retained. The follow up
work [1] will need to be built around the new feature provisioning
uAPI, with which it's easier to formalize migration compatibility
support at the driver level.

Thanks,
-Siwei
