Davide Caratti e7a98a96f0 mptcp: unbreak JSON endpoint list
the following command:

 # ip -j mptcp endpoint show

prints a JSON array that misses the terminating bracket. Fix this calling
delete_json_obj() to balance the call to new_json_obj().

Jianguo Wu 7f1d58d1a1 mptcp: make sure flag signal is set when add addr with port
When add address with port, it is mean to send an ADD_ADDR to remote,
so it must have flag signal set.

Florian Westphal ff619e4fd3 mptcp: add support for event monitoring
This adds iproute2 support for mptcp event monitoring, e.g. creation,
establishment, address announcements from the peer, subflow establishment
and so on.

While the kernel-generated events are primarily aimed at mptcpd (e.g. for
subflow management), this is also useful for debugging.

This adds print support for the existing events.

Sample output of 'ip mptcp monitor':
[       CREATED] token=83f3a692 remid=0 locid=0 saddr4=10.0.1.2 daddr4=10.0.1.1 sport=58710 dport=10011
[   ESTABLISHED] token=83f3a692 remid=0 locid=0 saddr4=10.0.1.2 daddr4=10.0.1.1 sport=58710 dport=10011
[SF_ESTABLISHED] token=83f3a692 remid=0 locid=1 saddr4=10.0.2.2 daddr4=10.0.1.1 sport=40195 dport=10011 backup=0

Paolo Abeni 42fbca91cd mptcp: add support for port based endpoint
The feature is supported by the kernel since 5.11-net-next,
let's allow user-space to use it.

Just parse and dump an additional, per endpoint, u16 attribute

Matthieu Baerts 3a53ff7e58 mptcp: show all endpoints when no ID is specified
According to 'ip mptcp help', 'endpoint show' can accept no argument:

  ip mptcp endpoint show [ id ID ]

It makes sense to print all endpoints when no filter is used.

So here if the following command is used, all endpoints are printed:

  ip mptcp endpoint show

Same as:

  ip mptcp endpoint

Paolo Abeni 7e0767cd86 add support for mptcp netlink interface
Implement basic commands to:
- manipulate MPTCP endpoints list
- manipulate MPTCP connection limits

Examples:
1. Allows multiple subflows per MPTCP connection
   $ ip mptcp limits set subflows 2

2. Accept ADD_ADDR announcement from the peer (server):
   $ ip mptcp limits set add_addr_accepted 2

3. Add a ipv4 address to be annunced for backup subflows:
   $ ip mptcp endpoint add 10.99.1.2 signal backup

4. Add an ipv6 address used as source for additional subflows:
   $ ip mptcp endpoint add 2001::2 subflow
