Replace DSCP/ECT/CE with DSCP/ECN for IPv6. Introduce short descriptions for DSCP/ECN values. Formating changes: - Make IPv4 and IPv6 as similar as possible. - Display short abbreviations only for "Differentiated Services Field". - Display DiffServ field as hex for IPv4. - Elide leading zeros from hex representation from DiffServ field for IPv6. - Display DSCP/ECN as decimal in subtree (same as "IP DSCP" column format).
