> The Mellanox NICs support SR-IOV and have E-Switch feature.
> When SR-IOV is set up in switchdev mode and E-Switch is enabled we have
> so called VF representors in the system. All representors belonging to the
> same E-Switch are created on the basis of the single PCI function and with
> current implementation each representor has its own dedicated Infiniband
> device and operates within its own Infiniband context. It is proposed to
> provide representors as ports of the single Infiniband device and operate on
> the shared Infiniband context saving various resources. This patch introduces
> appropriate structures.
> 
> Also the functions to allocate and free shared IB context for multiport are
> added. The IB device context, Protection Domain, device attributes,
> Infiniband names are going to be relocated to the shared structure from the
> device private one.
> mlx5_dev_spawn() is updated to support shared context.
