even if MPTCP handling is enabled via the "enabled" flag, it is ignored per-address family unless NetworkManager configures a default route. With this flag, NetworkManager will also configure MPTCP endpoints if there is no default route. This takes effect per-address family.
even if MPTCP handling is enabled via the "enabled" flag, it is ignored unless "/proc/sys/net/mptcp/enabled" is on. With this flag, MPTCP endpoints will be configured regardless of the sysctl setting.
Flag for the MPTCP endpoint. If this is a subflow endpoint, the subflows created using this endpoint will have the backup flag set during the connection process. This flag instructs the peer to only send data on a given subflow when all non-backup subflows are unavailable. This does not affect outgoing data, where subflow priority is determined by the backup/non-backup flag received from the peer
don't configure MPTCP endpoints on the device.
MPTCP is enabled and endpoints will be configured. This flag is implied if any of the other flags indicate that MPTCP is enabled and therefore in most cases unnecessary. Note that if "/proc/sys/net/mptcp/enabled" sysctl is disabled, MPTCP handling is disabled despite this flag. This can be overruled with the "also-without-sysctl" flag. Note that by default interfaces that don't have a default route are excluded from having MPTCP endpoints configured. This can be overruled with the "also-without-default-route" and this affects endpoints per address family.
Flag for the MPTCP endpoint. If this is a subflow endpoint and additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow for each known peer address, using this endpoint as the source address. This will occur after the MPTCP connection is established. If the peer did not announce any additional addresses using the MPTCP ADD_ADDR sub-option, this will behave the same as a plain subflow endpoint. When the peer does announce addresses, each received ADD_ADDR sub-option will trigger creation of an additional subflow to generate a full mesh topology.
The default, meaning that no MPTCP flags are set.
Flag for the MPTCP endpoint. The endpoint will be announced/signaled to each peer via an MPTCP ADD_ADDR sub-option.
Flag for the MPTCP endpoint. If additional subflow creation is allowed by the MPTCP limits, the MPTCP path manager will try to create an additional subflow using this endpoint as the source address after the MPTCP connection is established.
