Currently ip-link(8) parses, but ignores "group" argument to
peer interface on veth creation.
Insert IFLA_GROUP attribute for peer interface when present.

This fixes crash when ip-link(8) invoced with command:
ip link add dev veth1a type veth peer
Use warn_unused_result to enforce checking return value of rtnl_send,
and fix where the errors are.
Suggested by initial patch from Petr Písař <ppisar@redhat.com>
Display more user friendly rates.
10Mbit is more readable than 10000Kbit
Before :

tbf support 64bit rates start from linux-3.13.
Add 64bit rates support in tc tools.

qdisc tbf 1: root refcnt 2 rate 40000Mbit burst 230000b peakrate 50000Mbit minburst 87500b lat 50.0ms

As a system admin I occasionally want to be able to check that all
interfaces has a name in DNS or /etc/hosts file.

Example:
$ ss state established \( sport = :4060 or sport = :4061 or sport = :4062 or sport = :4063 or sport = :4064 or sport = :4065 or sport = :4066 or sport = :4067 \) > /dev/null
Aborted
In the example above ssfilter_bytecompile(...) will return (int)136.
char l1 = 136; means -120 which will result in a negative number
being passed to malloc at misc/ss.c:913.
Simply declare l1 and l2 as integers to avoid the char overflow.
This is one of the issues originally reported in http://bugs.debian.org/511720
Fix the same problem in other code paths as well (thanks to Eric Dumazet).

As both linux kernel and function ipaddrlabel_modify use unsigned int for
label. We should also use unsigned int value when print addrlabel in case of
misunderstanding.

There are two global variables in tc/tc_class.c:
__u32 filter_qdisc;
__u32 filter_classid;
These are not re-initialized for each line received in -batch mode:
class show dev eth0 parent 1: classid 1:1
class show dev eth0 parent 1: classid 1:1
Error: duplicate "classid": "1:1" is the second value.
This patch fixes the issue by initializing the two globals when we
enter print_class().

tc: allow qdisc without options
ip xfrm considers that the user-defined mark is "any" as soon as
(mark.v & mark.m == 0), which prevents from specifying non-wildcard
marks that include the value 0 (typically 0/0xffffffff).
Yet, matching exactly mark 0 is useful for instance to separate
vti policies from global policies.
Always configure the user mark if mark.m != 0.

TCA_HTB_DIRECT_QLEN attribute is supported since linux-3.10
HTB classes use an internal pfifo queue, which limit was not reported
by tc, and value inherited from device tx_queue_len at setup time.
With this patch, tc displays the value and can change it.
