I do have some concern about this behavior change, 'port_is_stopped' and ' cmd_reconfig_device_queue '.
1, seems this behavior change is not necessary for using the new offload API. Maybe splitting this patch to 2 is better.
2, some NICs doesn't need to be stopped or re-configured to make vlan functions enabled. That's why the original code doesn't have this restriction. Maybe figuring out a way to do the restriction in the driver layer is better.
