> Subject: [PATCH] net/i40e: fix single VLAN cannot work normal
>
> After disable QinQ, single VLAN can not work normal.
> The reason is that QinQ is not disabled correctly.
>
> Before configuring QinQ, need to back up and clean MAC/VLAN filters of all
> ports. After configuring QinQ, restore MAC/VLAN filters of all ports. When
> disable QinQ, need to set valid_flags to 0x0008 and set first_tag to 0x88a8.
