Summary of changes: - Add VMCI_VMWZC_DST_RID to the reserved hypervisor datagram resource id enum and bump VMCI_RESOURCE_MAX accordingly
The hypervisor-side zero-copy buffer sharing service occupies its own resource id in the hypervisor datagram namespace. Reserve a name for it alongside the existing entries rather than leaving callers to open-code the number, following the procedure described in that enum's own comment: the set of resource ids available in the hypervisor is fixed and statically known, and a new caller extends it by incrementing the maximum. VMCI_RESOURCE_MAX has no in-tree users, so the bump does not affect existing code. The new entry likewise has no in-tree user until the vmw_zerocopy driver, added later in this series, references it.
