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.
Note: This patch might conflict with pds_vfio patches that are
in review, depending on which patchset gets pulled first.

It's a bit weird to add code in one patch then move it
in another. Why not start with it in the final location?
Yes, and I usually try to catch those things before they go out :-). In
this case the chunk we're moving was added in the pds_core patchset a
few weeks ago, and since then we have realized it would be better to be
localized to the adminq header. Perhaps this would have been clearer if
this patch came first?
More importantly, the use of adminq terminology here
is a going to be somewhat confusing with the unrelated
admin virtqueue just having landed in the virtio spec.
Is this terminology coming from some hardware spec?
This firmware adminq through the PCI interface is similar to how several
other network drivers have an adminq for more complex conversations with
the FW. Yes, I can see how having both this device adminq and the
virtio admin VQ in one place could be confusing, and we'll need to be
sure to be clear in the difference. This is part of why we put most of
the adminq cmd code in its own cmd.c file, away from the virtio/vdpa
handling in vdpa_dev.c.
Thanks,
