Added new '-g[raph]' option which shows classes in the graph view.

Meanwhile only generic stats info output is supported.

Extend "ip-address" man page to reflect the recent extension of
allowing to list addresses with flags tentative, deprecated, dadfailed
not being set.
Signed-off-by: Heiner Kallweit <heiner.kallweit@web.de>

Currently self is set internally only if hwmode is set.
This makes it necessary for the hw to have a mode.
There is no hwmode really required to go to hardware. So, introduce
self for anybody who wants to target hardware.

v1 -> v2
    - fix a few bugs. Initialize flags to zero: this was required to
    keep the current behaviour unchanged.

Added new option 'type' to 'ip link show'
command which allows to filter devices by type:

    ip link show type bridge
    ip link show type vlan
Signed-off-by: Vadim Kochan <vadim4j@gmail.com>

Sometimes it's needed to have "ip address show" list only addresses
with certain flags not being set, e.g. in network scripts.
As an example one might want to exclude addresses in "tentative"
or "deprecated" state.

Support listing addresses with flags tentative, deprecated, dadfailed
not being set by prefixing the respective flag with a minus.

Remove all trailing whitespace and space before tabs.

Checking by SS_CLOSE state was remowed in:

    (45a4770b) ss: Remove checking SS_CLOSE state for packet and netlink

which is not really correct because now by default all sockets are seen
when do 'ss'.

Here is most correct fix which considers specified family.

To see netlink sockets:
    ss -A netlink

To see packet sockets:
    ss -A packet

And ss by default will show only connected/established sockets as it
was before all the time.

Replaced handling netlink messages by rtnl_dump_filter
from lib/libnetlink.c, also:

    - removed unused dump_fp arg;
    - added MAGIC_SEQ #define for 123456 seq id;
    - silently exit if ENOENT errno is caused for NETLINK_SOCK_DIAG proto
        in lib/libnetlink.c: rtnl_duml_filter_l(...) function. This fix
        was added in a3fd8e58 by Eric

Go back to kernel version of if_bridge.h and use patched
version of linux/in6.h and libc-compat.h

Needs to be built at runtime.

Now it is posible to filter by existing Netlink protos:

    ss -A netlink src uevent
    ss -A netlink src nft
    ss -A netlink src genl

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

Add NTF_EXT_LEARNED flag to neigh flags to indicate FDB entry learned by
device has been learned externally to bridge FDB.  For these entries,
add "external" annotation in bridge fdb show output:

  00:02:00:00:03:00 dev swp2 used 2/2 master br0 external
  00:02:00:00:03:00 dev swp2 self permanent

In the example above, 00:02:00:00:03:00 is shown twice on dev swp2.  The
first entry if from the bridge (master) and is marked as "external" by
the offload device.  The second entry is from the brport offload device (self),
and was learned by the device.

This permits to selectively enable explicit congestion notification via
the routing table.

If this ecn feature is not set, the kernel will use the tcp_ecn sysctl
to decide wheter to use ECN when establising a TCP connection.

At the time of this writing, the kernel supports ecn and allfrags, but
allfrags is of dubious value and not implemented here.
