ip link: Add ipvlan support to the iproute2/ip util

Adding basic support to create virtual devices using 'ip'
utility. Following is the syntax -

	ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ]
	e.g. ip link add link eth0 ipvl0 type ipvlan mode l3

ip route: enable per-route ecn settings via 'features' option

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.

Example:

ip route change 192.168.2.0/24 dev eth0 features ecn

bridge/fdb: add flag/indication for FDB entry synced from offload device

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.

ipaddress: enable -details option

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

ss: Use rtnl_dump_filter in handle_netlink_request

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 a3fd8e58c1787af186f5c4b234ff974544f840b6 by Eric
        for misc/ss.c

ss: Dont show netlink and packet sockets by default

Checking by SS_CLOSE state was remowed in:

    (45a4770bc0) 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.

ip: allow ip address show to list addresses with certain flags not being set

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.

bridge link: add option 'self'

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.

v2 -> v3
    - fix comment
