The pds_core_logical_qtype enum and IFNAMSIZ are not needed
in the common PDS header, only needed when working with the
adminq, so move them to the adminq header.

This patchset implements a new module for the AMD/Pensando DSC that
supports vDPA services on PDS Core VF devices. This code is based on
and depends on include files from the pds_core driver described here[0].
The pds_core driver creates the auxiliary_bus devices that this module
connects to, and
To add a bit of vendor flexibility with various virtio based devices,

field to struct virtio_pci_modern_device. If defined by the driver,
this mask will be used in a call to dma_set_mask_and_coherent() instead
of the tradition
To add a bit of vendor flexibility with various virtio based devices,

Btw, if this tests out good and we end up doing this, I think we

When map() is called on a detached domain, the domain does not exist in
the device so we do not send a MAP request, but we do update the
internal mapping tree, to be replayed on the next attach. Since this
constitutes a successful iommu_map() call, return *mapped in this case
too.

When an endpoint is released, for example a PCIe VF being destroyed or a
function hot-unplugged, it should be detached from its domain. Send a
DETACH request.
