> A vNTB PCI function can now expose endpoint-local DMA channels to its
> host. Decode the extension and register the advertised channels before
> the NTB device, so clients of that NTB device can use the DMA
> functionality in the same PCI function. Endpoints without the extension,
> or hosts without support for its DMA type or with no DMA IRQ available,
> continue without DMA.
>
> Only DW eDMA is supported for now. Dispatch on the advertised DMA type
> and keep type-specific setup in local helpers. Support for another
> implementation can add a new case and its own helpers.
