+ * Description:
+ * NDMPv0, represented here, is a ficticious version
+ * used to negotiate NDMP protocol version for the
+ * remainder of the session. Early, as a connection is
+ * being set up, the version of the protocol is unknown.
+ * The first messages exchanged negotiate the protocol
+ * version, and such messages are in the NDMP format.
+ * This is different than other protocols, such as ONC RPC
+ * which negotiate version by lower layers before the
+ * objective protocol becomes involved. During the
+ * negotiation, we deem the connection to be in "v0" mode.
+ * This NDMPv0 protocol specification is the subset of
+ * the NDMP protocol(s) required for the negotiation,
+ * and necessarily must remain immutable for all time.
