This patch fixes the following issues which was introduced by me in commits:

    #1 (2dc85485) ss: Fixed broken output for Netlink 'Peer Address:Port' column
    ISSUE: Broken layout when all sockets are printed out

    #2 (eef43b50) ss: Identify more netlink protocol names
    ISSUE: Protocol id is not printed if 'numbers only' output was specified (-n)

Also aligned the width of the local/peer ports to be more wider.

I tested with a lot of option combinations (I may miss some test cases),
but layout seems to me better than the previous released version of iproute2/ss.

Adding in6.h breaks build with redefined values.

The issue was observed when IPv6 router broadcasted NDUSEROPT
messages which are not handled by monitor and caused printing
'Timestamps' w/o message because such kind of rtnl messages is not
handled by monitor.

As 'ip monitor' by default subscribes to the all mcast rtnl groups except
RTGRP_TC then all messages of these rtnl groups which are not handled by
monitor may cause such issues.

Fixed by subscribing by default to rtnl mcast groups which are
supported by 'ip monitor'.

This option was used only for 'ip link', but it can be useful to have it for
'ip address'. Thus it is possible to display link details and addresses with one
command.

Example:
$ ip -d a ls dev gre1
9: gre1@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1468 qdisc noqueue state UNKNOWN group default
    link/gre 10.16.0.249 peer 10.16.0.121 promiscuity 0
    gre remote 10.16.0.121 local 10.16.0.249 ttl inherit ikey 0.0.0.10 okey 0.0.0.10 icsum ocsum
    inet 192.168.0.249 peer 192.168.0.121/32 scope global gre1
       valid_lft forever preferred_lft forever
    inet6 fe80::5efe:a10:f9/64 scope link
       valid_lft forever preferred_lft forever

I dont see a reason that packet and netlink states will be
printed only if SS_CLOSE state is set in filter, in that case
to print states of netlink or packet sockets it is needed to run:

    ss -A netlink state close

instead of:

    ss -A netlink

As 'ip' util will share the same netns from the caller
process then we can just look at /proc/self/.. to show

Signed-off-by: Tom Herbert <therbert@google.com>

This patch adds support to configure foo-over-udp (FOU) and Generic
UDP Encapsulation for GRE tunnels. This configuration allows selection
of FOU or GUE for the tunnel, specification of the source and
destination ports for UDP tunnel, and enabling TX checksum. This
configuration only affects the transmit side of a tunnel.

Example:

ip link add name tun1 type gre remote 192.168.1.1 local 192.168.1.2 \
   ttl 225 encap fou encap-sport auto encap-dport 7777 encap-csum

This would create an GRE tunnel in GUE encapsulation where the source
port is automatically selected (based on hash of inner packet) and
checksums in the encapsulating UDP header are enabled.

Added 'ip fou...' commands to enable/disable UDP ports for doing
foo-over-udp and Generic UDP Encapsulation variant. Arguments are port
number to bind to and IP protocol to map to port (for direct FOU).

Examples:

ip fou add port 7777 gue
ip fou add port 8888 ipproto 4

The first command creates a GUE port, the second creates a direct FOU
port for IPIP (receive payload is a assumed to be an IPv4 packet).

Width is the maximum number of characters used for the value, excluding a
field separator. So append a single whitespace.

Add a new -iec option in addition to -human.
Cleanup code so the formatting of numbers is done in one function,
not 2 ways and 2 sizes.

Byte and packet count can increase to really big numbers. This adds a
switch to show human readable output.

- any ipv6 tunnel mode (proto == 0) could not be set
due to incomplete set of cases in do_add, do_del.
- vti6 logic was inverted: it was using "ip6_vti0" basedev
UNLESS mode is set to vti6.

We don't need a switch by p.proto in do_add()/do_del(): it
already exists in parse_args(). So if parse_args() call
was successful, no need to check tunnel mode again.
