The goal of this patch is to test during the runtime if the command RTM_GETNSID
is supported by the kernel.

If '-nm' specified that do not fail if there is no

Changed default class name file cls_names -> tc_cls.

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.

commit f3a2ddc124 ("lib utils: Use helpers to get AF bit/byte len")
used a wrong family or family of zero in the default case
during af_bit_len calculation causing ip route commands to
fail with below error
Error: an inet prefix is expected rather than "10.0.2.14/24".

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.

This patch replaces exits with returns in several
iproute2 commands. This fixes `ip -batch -force`
to not exit but continue on errors.
$cat c.txt
route del 1.2.3.0/24 dev eth0
route del 1.2.4.0/24 dev eth0
route del 1.2.5.0/24 dev eth0
route add 1.2.3.0/24 dev eth0

While looking at the manpage, I noticed a reference to 'embedded' that was
added by this commit:

iproute2: bridge: finish removing replace option in man pages
I no longer see any reference to the 'embedded' option in any c- or h-files, so
it seems worthwhile to remove.

Where used in the ip tool, the 'show' option always has the synonyms
'list' and 'lst', except for ip-token and ip-addrlabel, which are missing
'lst'. Add this as a synonym for these commands.

This patch adds support to specify 'master' keyword,
to target a bridge link command explicitly to the software
bridge driver.
Adds self/master keywords to usage and man page

fix usage to say (self and master) and not (self or master)

The existing behaviour forces one to memorize the integer constants for
STP port states.
# bridge link set dev dummy0 state 3
This patch makes it possible to use the lowercased port state name.
# bridge link set dev dummy0 state forwarding
Invalid non-integer inputs now cause exit with status -1.

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)
