The OCXL specification supports distributing acTags amongst different AFUs and functions on the link. The platform-specific acTag range for the link is obtained using the OCXL provider services and then assigned to the host function based on implementation. For cxlflash devices only a single function per host is expected and thus the entire range is assigned. Signed-off-by: Uma Krishnan <redacted> Acked-by: Matthew R. Ochs <redacted>

These could be u16s.
