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

BEFORE:
The show command has additional formatting options:
-s, -stats, -statistics
output more statistics about packet usage.
-d, -details
output more detailed information.
-h, -human, -human-readble
output statistics with human readable values number followed by suffix
-iec print human readable rates in IEC units (ie. 1K = 1024).

When output the netlink sockets:
ss -A netlink state close
the layout is a little broken with a shifted 'Peer Address:Port'
stars and empty new lines. Fixed by making the port field to be
wider for 'Local Address:Port' column.

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
the netns of the current process by:
ip netns id

There were only few Netlink protocol names
which were printed on the screen:
rtnl, fw, tcpdiag
So added the ability to identify Netlink proto name
from /etc/iproute/nl_protos or from static table.

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).

- 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.

Starting from linux-3.15 (commit 9063e21fb026, "netlink: autosize skb
lengths"), kernel is able to send up to 16K in netlink replies.
This change enables iproute2 commands to get bigger chunks,

Such approach allows to run *.t scripts from any
tests/ subdirectories.
One point is that tests from tests/cls/*.t (which are needed
by tests/cls-testbed.t but does not exist yet) will also
be ran aside with tests/cls-testbed.t which is not good
because in such case they will be ran twice, so renamed these
tests path to tests/cls/*.c in tests/cls-testbed.t
