The [PFIFO] section manages the queueing discipline (qdisc) of
Packet First In First Out (pfifo).
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 number of packets in the FIFO
queue. The size limit prevents overflow in case the kernel is
unable to dequeue packets as quickly as it receives them.
When this limit is reached, incoming packets are dropped. An
unsigned integer in the range 0–4294967294. Defaults to unset
and kernel's default is used.
