MPTCP handling is enabled -or disabled depending on whether a /0 default route (either IPv4 or IPv6) is -configured in the main routing table.
+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.
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.
+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.
+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.
