+ * Network Service Type for option SO_NET_SERVICE_TYPE
+ *
+ * The vast majority of sockets should use Best Effort that is the default
+ * Network Service Type. Other Network Service Types have to be used only if
+ * the traffic actually matches the description of the Network Service Type.
+ *
+ * Network Service Types do not represent priorities but rather describe
+ * different categories of delay, jitter and loss parameters.
+ * Those parameters may influence protocols from layer 4 protocols like TCP
+ * to layer 2 protocols like Wi-Fi. The Network Service Type can determine
+ * how the traffic is queued and scheduled by the host networking stack and
+ * by other entities on the network like switches and routers. For example
+ * for Wi-Fi, the Network Service Type can select the marking of the
+ * layer 2 packet with the appropriate WMM Access Category.
+ *
+ * There is no point in attempting to game the system and use
+ * a Network Service Type that does not correspond to the actual
+ * traffic characteristic but one that seems to have a higher precedence.
+ * The reason is that for service classes that have lower tolerance
+ * for delay and jitter, the queues size is lower than for service
+ * classes that are more tolerant to delay and jitter.
+ *
+ * For example using a voice service type for bulk data transfer will lead
+ * to disastrous results as soon as congestion happens because the voice
+ * queue overflows and packets get dropped. This is not only bad for the bulk
+ * data transfer but it is also bad for VoIP apps that legitimately are using
+ * the voice service type.
+ *
+ * The characteristics of the Network Service Types are based on the service
+ * classes defined in RFC 4594 "Configuration Guidelines for DiffServ Service
+ * Classes"
+ *
+ * When system detects the outgoing interface belongs to a DiffServ domain
+ * that follows the recommendation of the IETF draft "Guidelines for DiffServ to
+ * IEEE 802.11 Mapping", the packet will marked at layer 3 with a DSCP value
+ * that corresponds to Network Service Type.
+ *
+ * NET_SERVICE_TYPE_BE
+ * "Best Effort", unclassified/standard. This is the default service
+ * class and cover the majority of the traffic.
+ *
+ * NET_SERVICE_TYPE_BK
+ * "Background", high delay tolerant, loss tolerant. elastic flow,
+ * variable size & long-lived. E.g: non-interactive network bulk transfer
+ * like synching or backup.
+ *
+ * NET_SERVICE_TYPE_RD
+ * "Responsive Data", a notch higher than "Best Effort", medium delay
+ * tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email,
+ * instant messaging, for which there is a sense of interactivity and
+ * urgency (user waiting for output).
+ *
+ * NET_SERVICE_TYPE_OAM
+ * "Operations, Administration, and Management", medium delay tolerant,
+ * low-medium loss tolerant, elastic & inelastic flows, variable size.
+ * E.g. VPN tunnels.
+ *
+ * NET_SERVICE_TYPE_AV
+ * "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium
+ * loss tolerant, elastic flow, constant packet interval, variable rate
+ * and size. E.g. video and audio playback with buffering.
+ *
+ * NET_SERVICE_TYPE_RV
+ * "Responsive Multimedia Audio/Video", low delay tolerant, low-medium
+ * loss tolerant, elastic flow, variable packet interval, rate and size.
+ * E.g. screen sharing.
+ *
+ * NET_SERVICE_TYPE_VI
+ * "Interactive Video", low delay tolerant, low-medium loss tolerant,
+ * elastic flow, constant packet interval, variable rate & size. E.g.
+ * video telephony.
+ *
+ * NET_SERVICE_TYPE_SIG
+ * "Signaling", low delay tolerant, low loss tolerant, inelastic flow,
+ * jitter tolerant, rate is bursty but short, variable size. E.g. SIP.
+ *
+ * NET_SERVICE_TYPE_VO
+ * "Interactive Voice", very low delay tolerant, very low loss tolerant,
+ * inelastic flow, constant packet rate, somewhat fixed size.
