Zbigniew Jędrzejewski-Szmek 949fb07e6e network: also change fair_queue_traffic_policing→fair_queueing 
Follow-up for ca58d00c68. I messed

Zbigniew Jędrzejewski-Szmek ca58d00c68 network: FairQueueTrafficPolicing→FairQueueing 
This never made into a release, so we can change the name with impunity.
Suggested by Davide Pesavento.

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 864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)

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.
