There have been several instances where response from kernel
has overrun the stack buffer from the caller. Avoid future problems
by passing a size argument.
Also drop the unused peer and group arguments to rtnl_talk.
It is hard to quickly find what you are looking for in the output of the
ip command. Color helps.
This patch adds a '-c' flag to highlight these with individual colors:
- interface name
- ip address
- mac address
- up/down state

Joining multicast group on ethernet level via "ip maddr" command would
not work if we have an Ethernet switch that does igmp snooping since
the switch would not replicate multicast packets on ports that did not
have IGMP reports for the multicast addresses.
Linux vxlan interfaces created via "ip link add vxlan" have the group option
that enables then to do the required join.
By extending ip address command with option "autojoin" we can get similar
functionality for openvswitch vxlan interfaces as well as other tunneling
mechanisms that need to receive multicast traffic.
example:
ip address add 224.1.1.10/24 dev eth5 autojoin
ip address del 224.1.1.10/24 dev eth5
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

"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.

Sometimes it's needed to have "ip address show" list only addresses
with certain flags not being set, e.g. in network scripts.
As an example one might want to exclude addresses in "tentative"
or "deprecated" state.
Support listing addresses with flags tentative, deprecated, dadfailed
not being set by prefixing the respective flag with a minus.

This option was used only for 'ip link', but it can be useful to have it for
'ip address'. Thus it is possible to display link details and addresses with one
command.
Example:
$ ip -d a ls dev gre1

Make ip address show accept the -s option similarly to ip link. This creates
an one command replacement for "ifconfig -a" useful for people who still
stay with ifconfig because of this feature.
Print the stats as the last thing for the interface. This requires some code
shuffling.

This patch avoids a full link wildump request when the user has specified
a single link. Uses RTM_GETLINK without the NLM_F_DUMP flag.
This helps on a system with large number of interfaces.
This patch currently only uses the link ifindex in the filter.
Hoping to provide a subsequent kernel patch to do link dump filtering on
other attributes in the kernel.
In iplink_get, to be safe, this patch currently sets the answer buffer
size to the max size that libnetlink rtnl_talk can copy. The current api
does not seem to provide a way to indicate the answer buf size.

o "min_tx_rate" option has been added for minimum Tx rate. Hence, for
consistent naming, "max_tx_rate" option has been introduced for maximum
Tx rate.
o Change in v2: "rate" can be used along with "max_tx_rate".
When both are specified, "max_tx_rate" should override.
o Change in v3:
* IFLA_VF_RATE: When IFLA_VF_RATE is used, and user has given only one of
min_tx_rate or max_tx_rate, reading of previous rate limits is done in
userspace instead of in kernel space before ndo_set_vf_rate.
* IFLA_VF_TX_RATE: When IFLA_VF_TX_RATE is used, min_tx_rate is always read
in kernel space. This takes care of below scenarios:
(1) when old tool sends "rate" but kernel is new (expects min and max)
(2) when new tool sends only "rate" but kernel is old (expects only "rate")
o Change in v4 as suggested by Stephen Hemminger:
* As per iproute policy, input and output formats should match. Changing display
of max_tx_rate and min_tx_rate options accordingly.

Kernel is being extended to support flag IFA_F_MANAGETEMPADDR also for
deletion of addresses. This will allow a userspace application to indicate
that for a global address the kernel should delete all related temporary
addresses as well.
"ip addr del" internally calls ipaddr_modify which silently accepts
any flag provided on the command line already, independent of the
actual command.
Therefore only the usage documentation needs to be extended.

commit 37c9b94ed2 (add support for extended ifa_flags)
introduced a regression:
# ./ip/ip addr add 192.168.0.1/24 dev eth0
RTNETLINK answers: Invalid argument
This is due to old kernels don't support IFA_FLAGS flag, we should not
use it if we don't use the flags beyond old .ifa_flags.

This is useful to know the 'real' status of an interface (the flag IFF_PROMISC
is exported by the kernel only when the user set it explicitly, for example it
will not be exported when a tcpdump is running).
This information will be displayed when '-details' is provided by the user.
Example:
$ ip -d l l tun10
6: tun10: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN mode DEFAULT
