I opted to add the "ing" ending. "Fair queuing" is the name of the general
concept and algorithm, and "Fair queue" is mostly used for the implementation
name.

Susant Sahani 9942b71089 network: tc introduce sfq - Stochastic Fairness Queueing
Stochastic Fairness Queueing is a classless queueing discipline.
SFQ does not shape traffic but only schedules the transmission of packets, based on 'flows'.
The goal is to ensure fairness so that each flow is able to send data in turn,
thus preventing any single flow from drowning out the rest.

Zbigniew Jędrzejewski-Szmek 800603524a networkd: drop DHCPv4 config on stop, keep on restart, by default
This partially reverts 95355a281c.

It seems that other parts of link_stop_clients() should be skipped
when restarting, but I don't know enough about those other clients to have
an opinion if it is better to stop&start them on restart or not.
Anyway, that can be done in later patches now that the support for restarts
is there.

Siddharth Chandrasekara afe42aef39 dhcp4: make IPServiceType configurable
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.
