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.
