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.

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

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).
