The [FairQueueingControlledDelay] section manages the queueing
discipline (qdisc) of fair queuing controlled delay (FQ-CoDel).
Parent=
Configures the parent Queueing Discipline (qdisc). Takes one
of "root", "clsact", "ingress" or a class identifier. The
class identifier is specified as the major and minor numbers
in hexadecimal in the range 0x1–Oxffff separated with a colon
("major:minor"). Defaults to "root".
Handle=
Configures the major number of unique identifier of the
qdisc, known as the handle. Takes a hexadecimal number in the
range 0x1–0xffff. Defaults to unset.
PacketLimit=
Specifies the hard limit on the real queue size. When this
limit is reached, incoming packets are dropped. Defaults to
unset and kernel's default is used.
MemoryLimitBytes=
Specifies the limit on the total number of bytes that can be
queued in this FQ-CoDel instance. When suffixed with K, M, or
G, the specified size is parsed as Kilobytes, Megabytes, or
Gigabytes, respectively, to the base of 1024. Defaults to
unset and kernel's default is used.
Flows=
Specifies the number of flows into which the incoming packets
are classified. Defaults to unset and kernel's default is
used.
TargetSec=
Takes a timespan. Specifies the acceptable minimum
standing/persistent queue delay. Defaults to unset and
kernel's default is used.
IntervalSec=
Takes a timespan. This is used to ensure that the measured
minimum delay does not become too stale. Defaults to unset
and kernel's default is used.
QuantumBytes=
Specifies the number of bytes used as the "deficit" in the
fair queuing algorithm timespan. When suffixed with K, M, or
G, the specified size is parsed as Kilobytes, Megabytes, or
Gigabytes, respectively, to the base of 1024. Defaults to
unset and kernel's default is used.
ECN=
Takes a boolean. This can be used to mark packets instead of
dropping them. Defaults to unset and kernel's default is
used.
CEThresholdSec=
Takes a timespan. This sets a threshold above which all
packets are marked with ECN Congestion Experienced (CE).
Defaults to unset and kernel's default is used.
