Keep ss output consistent and format DCTCP socket statistics similar to skmen
and timer where a group of logical values are grouped by brackets. This makes
parser scripts *and* humans more happy.

Current output of 'ss -inetm dst :80':

The existing behaviour forces one to memorize the integer constants for
STP port states.

This patch makes it possible to use the lowercased port state name.

When this attribute is set, it means that the i/o part of the related netdevice
is in another netns.

This new attribute is now advertised by the kernel for x-netns interfaces.
It's also possible to set it when an interface is created (and thus creating a
x-netns interface with one single message).

Example:
 $ ip netns add foo
 $ ip netns add bar
 $ ip -n foo netns set bar 15
 $ ip -n foo link add ipip1 link-netnsid 15 type ipip remote 10.16.0.121 local 10.16.0.249
 $ ip -n foo link ls ipip1
 3: ipip1@NONE: <POINTOPOINT,NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default
     link/ipip 10.16.0.249 peer 10.16.0.121 link-netnsid 15

The kernel now provides ids for peer netns. This patch implements a new command
'set' to assign an id.
When netns are listed, if an id is assigned, it is now displayed.

Example:
 $ ip netns add foo
 $ ip netns set foo 1
 $ ip netns
 foo (id: 1)

Add section for additional arguments to GRE, IPIP, and SIT types

This patch adds support to remote checksum checksum offload
confinguration for IPIP, SIT, and GRE tunnels. This patch
adds a [no]encap-remcsum to ip link command which applicable
when configured tunnels that use GUE.

http://tools.ietf.org/html/draft-herbert-remotecsumoffload-00

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 \
   encap-remcsum

This would create an GRE tunnel in GUE encapsulation where the source
port is automatically selected (based on hash of inner packet),
checksums in the encapsulating UDP header are enabled (needed.for
remote checksum offload), and remote checksum ffload is configured to
be used on the tunnel (affects TX side).

This patch makes CAN_CTRLMODE_FD_NON_ISO netlink feature configurable.

During the CAN FD standardization process within the ISO it turned out that
the failure detection capability has to be improved.

The CAN in Automation organization (CiA) defined the already implemented CAN
FD controllers as 'non-ISO' and the upcoming improved CAN FD controllers as
'ISO' compliant. See at http://www.can-cia.com/index.php?id=1937

Starting with the - currently non-ISO - driver for M_CAN v3.0.1 introduced in
Linux 3.18 this bit needs to be propagated to userspace. In future drivers this
bit will become configurable depending on the CAN FD controllers capabilities.

"ip addr show up" would exclude the interface (link), but include the
addresses of down interfaces (which looked like they where indented
under a different interface). This fixes the filtering.

Allow delete all namespace names by:

    $ ip -all netns del
Signed-off-by: Vadim Kochan <vadim4j@gmail.com>

This change allows to exec some cmd on each
named netns (except default) by specifying '-all' option:

    # ip -all netns exec ip link

Each command executes synchronously.

Exit status is not considered, so there might be a case
that some CMD can fail on some netns but success on the other.

EXAMPLES:

1) Show link info on all netns:

$ ip -all netns exec ip link

netns: test_net
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
4: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 500
    link/ether 1a:19:6f:25:eb:85 brd ff:ff:ff:ff:ff:ff

netns: home0
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
4: tap0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 500
    link/ether ea:1a:59:40:d3:29 brd ff:ff:ff:ff:ff:ff

netns: lan0
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether ce:49:d5:46:81:ea brd ff:ff:ff:ff:ff:ff

2) Set UP tap0 device for the all netns:

$ ip -all netns exec ip link set dev tap0 up

netns: test_net

netns: home0

netns: lan0
