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.

[1] [PATCH v3 0/4] vDPA: initial config export via "vdpa dev show"
https://lore.kernel.org/virtualization/[email protected]/
1-6 look like bugfixes right?
1 and 2 are bug fixes, 3-5 you can say are bug fix for device_features,
but they would lay the ground for standardizing device_features
assumptions for drivers. Patch 6 is adding device_features to mlx5_vdpa
as you can recognize.
(please match the corresponding patch in the v2 series)
Thanks,
