c079e121a7 libnetlink: add size argument to rtnl_talk 
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.

d954b34a1f tc class: Show classes as ASCII graph 
Added new '-g[raph]' option which shows classes in the graph view.

Meanwhile only generic stats info output is supported.

e.g.:

$ tc/tc -g class show dev tap0

9bea14ff6b Fix tc stats when using -batch mode 
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().

cd70f3f522 libnetlink: remove unused junk callback 
Both rtnl_talk and rtnl_dump had a callback for handling portions
of netlink message that do not match the correct pid or seq.
But this callback was never used by any part of iproute2 so remove
it.

f4a8b23d39 Filter class output by classid 
Sometimes while dividing bandwidth by classes it is useful to see how some
specific class doing things live.

Which my simple patch it is possible to do
watch -n1 "tc -s -d class show dev eth0.2022 classid 1:1520"
and to get live statistics, how packets queued or dropped, and how much
bandwidth used (if estimator defined) for specific class.

e5d179d815 Fixes for tc help commands 
* "tc [class|qdisc|filter] get" doesn't exist, remove it from inline help.

* Add "replace" to "tc [class|filter] get" inline help.

* Fix "tc [class|qdisc|filter] help" output:

  ~$ tc class help
  [snip]
  Command "help" is unknown, try "tc class help".
  ~$

with my best wishes,

5bec34845b This patch adds ability to monitor tc events similar to ipmonitor. 
User runs "tc monitor" (without quotes) and watches events of
addition, deletion and updates from qdiscs, classes, filters and
actions as they happen.
