From: Chengwen Feng <fengcheng...@huawei.com>
In the HIP08 platform, the PF driver will notify VF driver to update
the PVID state [1], and VF will declare support QinQ insert when PVID
is disabled.
In the later platform (e.g. HIP09), the hardware has been improved,
so the PF driver will NOT notify VF driver to update the PVID state.
However, the later platform still have constraint: PVID and QinQ insert
cannot be enabled at the same time, otherwise, the hardware discards
packets and reports an error interrupt.
Plus, as far as we known, VF driver's users don't use the QinQ insert.
Therefore, we declare that the VF driver don't support QinQ insert.
