When looking at the rendered HTML version, we can see 'pm_type' is not
displayed with a bold font:
https://docs.kernel.org/5.19/networking/mptcp-sysctl.html
The empty line under 'pm_type' is then removed to have the same style as
the others.

MPTCP Sysfs variables
|
|
=====================
|
|
|
|
/proc/sys/net/mptcp/* Variables
|
|
===============================
|
|
|
|
enabled - BOOLEAN
|
|
Control whether MPTCP sockets can be created.
|
|
|
|
MPTCP sockets can be created if the value is 1. This is a
|
|
per-namespace sysctl.
|
|
|
|
Default: 1 (enabled)
|
|
|
|
add_addr_timeout - INTEGER (seconds)
|
|
Set the timeout after which an ADD_ADDR control message will be
|
|
resent to an MPTCP peer that has not acknowledged a previous
|
|
ADD_ADDR message.
|
|
|
|
The default value matches TCP_RTO_MAX. This is a per-namespace
|
|
sysctl.
|
|
|
|
Default: 120
|
|
|
|
checksum_enabled - BOOLEAN
|
|
Control whether DSS checksum can be enabled.
|
|
|
|
DSS checksum can be enabled if the value is nonzero. This is a
|
|
per-namespace sysctl.
|
|
|
|
Default: 0
|
|
|
|
allow_join_initial_addr_port - BOOLEAN
|
|
Allow peers to send join requests to the IP address and port number used
|
|
by the initial subflow if the value is 1. This controls a flag that is
|
|
sent to the peer at connection time, and whether such join requests are
|
|
accepted or denied.
|
|
|
|
Joins to addresses advertised with ADD_ADDR are not affected by this
|
|
value.
|
|
|
|
This is a per-namespace sysctl.
|
|
|
|
Default: 1
|
|
|
|
pm_type - INTEGER
|
|
Set the default path manager type to use for each new MPTCP
|
|
socket. In-kernel path management will control subflow
|
|
connections and address advertisements according to
|
|
per-namespace values configured over the MPTCP netlink
|
|
API. Userspace path management puts per-MPTCP-connection subflow
|
|
connection decisions and address advertisements under control of
|
|
a privileged userspace program, at the cost of more netlink
|
|
traffic to propagate all of the related events and commands.
|
|
|
|
This is a per-namespace sysctl.
|
|
|
|
* 0 - In-kernel path manager
|
|
* 1 - Userspace path manager
|
|
|
|
Default: 0
|
|
|
|
stale_loss_cnt - INTEGER
|
|
The number of MPTCP-level retransmission intervals with no traffic and
|
|
pending outstanding data on a given subflow required to declare it stale.
|
|
The packet scheduler ignores stale subflows.
|
|
A low stale_loss_cnt value allows for fast active-backup switch-over,
|
|
an high value maximize links utilization on edge scenarios e.g. lossy
|
|
link with high BER or peer pausing the data processing.
|
|
|
|
This is a per-namespace sysctl.
|
|
|
|
Default: 4
