[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 0/5] vDPA/ifcvf: implement immediate initialization mechanism
Formerly, ifcvf driver has implemented a lazy-initialization mechanism
for the virtqueues and other config space contents,
it would store all configurations that passed down from the userspace,
then load them to the device config space upon DRIVER_OK.
This can not serve live migration, so this series implement an
immediate initialization mechanism, which means rather than the
former store-load
