Subject: [PATCH v13 06/10] mmio: document ADMIN_VQ as reserved
Adding relevant registers needs more work and it's not clear what the use-case will be as currently only the PCI transport is supported. But let's keep the door open on this. We already say it's reserved in a central place, but it does not hurt to remind implementers to mask it. Signed-off-by: Michael S.
