driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICX1ZY CVE: NA ---------------------------------------------------------------------- In special scenarios involving duplicate migrations, after the first migration is completed, if the original VF device is used again and then migrated to another destination, the state indicating data migration completion for the VF device is not reset. This results in the second migration to the destination being skipped without performing data migration. After the modification, it ensures that a complete data migration is performed after the subsequent migration.
