>=20
> From: Long Li <longli@microsoft.com>
>=20
> For outgoing packets, the PF requires the VF to configure the vport with
> corresponding protection domain and doorbell ID for the kernel or user
> context. The vport can't be shared between different contexts.
>=20
> Implement the logic to exclusively take over the vport by either the
> Ethernet device or RDMA device.
