Next argument after the tc opcode/verdict is optional, using NEXT_ARG()
requires to have another argument after that one otherwise tc will bail
out. Therefore, we need to advance to the next argument manually as done
elsewhere.

Don't insert newline in -o (oneline) mode; print mark as hex.

Oneline mode is supposed to force all output to be on oneline and
machine-parsable, but this isn't the case for "ip xfrm" as shown:

% ip -o xfrm monitor
...
src 0.0.0.0/0 dst 0.0.0.0/0 \   dir out priority 2051 ptype main \  mark -1879048191/0xffffffff
    tmpl src 203.0.130.10 dst 198.51.130.30\        proto esp reqid 16384 mode tunnel\
...

as that's 2 lines, not one. Also, the "mark" is shown in signed
decimal, but the mask is in hex. This is confusing: let's use
hex for both.

It is possible to use class names from file /etc/iproute2/cls_names
which tc will use when showing class info:

Keep ss output consistent and format DCTCP socket statistics similar to skmen

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

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.

 $ ip netns add foo

 $ ip netns
 foo (id: 1)
