vfio/migration: Store VFIO migration flags in VFIOMigration
|
||
|
|
|
||
|
|
VFIO migration flags are queried once in vfio_migration_init(). Store
|
||
|
|
them in VFIOMigration so they can be used later to check the device's
|
||
|
|
migration capabilities without re-querying them.
|
||
|
|
|
||
|
|
This will be used in the next patch to check if the device supports
|
||
|
|
precopy migration.
