+ * NetBSD uses 15 for HIPPI.
+ *
+ * From a quick look at sys/net/if_hippi.h and sys/net/if_hippisubr.c
+ * in an older version of NetBSD , the header appears to be:
+ *
+ * a 1-byte ULP field (ULP-id)?
+ *
+ * a 1-byte flags field;
+ *
+ * a 2-byte "offsets" field;
+ *
+ * a 4-byte "D2 length" field (D2_Size?);
+ *
+ * a 4-byte "destination switch" field (or a 1-byte field
+ * containing the Forwarding Class, Double_Wide, and Message_Type
+ * sub fields, followed by a 3-byte Destination_Switch_Address
+ * field?, HIPPI-LE 3.4-style?);
+ *
+ * a 4-byte "source switch" field (or a 1-byte field containing the
+ * Destination_Address_type and Source_Address_Type fields, followed
+ * by a 3-byte Source_Switch_Address field, HIPPI-LE 3.4-style?);
+ *
+ * a 2-byte reserved field;
+ *
+ * a 6-byte destination address field;
+ *
+ * a 2-byte "local admin" field;
+ *
+ * a 6-byte source address field;
+ *
+ * followed by an 802.2 LLC header.
+ *
+ * This looks somewhat like something derived from the HIPPI-FP 4.4
+ * Header_Area, followed an HIPPI-FP 4.4 D1_Area containing a D1 data set
+ * with the header in HIPPI-LE 3.4 (ANSI X3.218-1993), followed by an
+ * HIPPI-FP 4.4 D2_Area (with no Offset) containing the 802.2 LLC header
+ * and payload? Or does the "offsets" field contain the D2_Offset,
+ * with that many bytes of offset before the payload?
+ *
+ * See http://wotug.org/parallel/standards/hippi/ for an archive of
+ * HIPPI specifications.
+ *
+ * RFC 2067 imposes some additional restrictions. It says that the
+ * Offset is always zero
+ *
+ * HIPPI is long-gone, and the source files found in an older version
+ * of NetBSD don't appear to be in the main CVS branch, so we may never
+ * see a capture with this link-layer type.
