+Subject: [PATCH] net/hns3: don't support QinQ insert for VF
+
+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.
