[PATCH virtio 0/4] pds_vdpa: mac, reset, and irq updates
v2 for internal review - heavily reworked NET_F_MAC patch, matches recent PR-68875 - reordered to put "clean and reset vqs" before "alloc-irq" to make them slightly simpler patches - other minor cleanups for simpler patches These are some fixes for device providing a MAC address, for allocating irq resources later to support vhost use, and for properly cleaning vq info

[PATCH 0/6] features provisioning fixes and mlx5_vdpa support
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.
