The MAC address of vport A in the hardware becomes invalid. If the address of vport A is changed to MAC address B, the driver needs to delete the MAC address A of vport A. Due to the MAC address A of vport A has become invalid in the hardware entry, so "-ENOENT" is returned. In this case, the "used_umv_size" value recorded in driver is not updated. As a result, the MAC entry status of the software is inconsistent with that of the hardware. Therefore, the driver updates the umv size even if the MAC entry cannot be found. Ensure that the software and hardware status is consistent.
