The new command is called "veth" with the following syntax:
* ip veth add <dev1> <dev2>
  creates interconnected pair of veth devices.
* ip veth del <dev>
  destroys the pair of veth devices, where <dev> is either
  <dev1> or <dev2> used to create the pair.

One question that is to be solved is whether or not to create
a hard-coded netlink family for veth driver. Without it the
family resolution code has to be moved to general place in ip
utility (by now it is copy-paste-ed from one file to another
till final decision).

Update headers
Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org>

This patch applies on top of Patrick McHardy's RTNETLINK
patches to add nested compat attributes.  This is needed to maintain
ABI for sch_{rr|prio} in the kernel with respect to tc.  A new option,
namely multiqueue, was added to sch_prio and sch_rr.  This will allow
a user to turn multiqueue support on for sch_prio or sch_rr at loadtime.
Also, tc qdisc ls will display whether or not multiqueue is enabled on
that qdisc.  When in multiqueue mode, a user can specify a value of 0 for
bands, and the number of bands will be created to match the number of
queues on the device.

This patch is to support the new sch_rr (round-robin) qdisc being proposed
in NET for multiqueue network device support in the Linux network stack.
It uses q_prio.c as the template, since the qdiscs are nearly identical,
outside of the ->dequeue() routine.

OK this patch fixes parsing of "action ...". I've removed
the erroring on unknown arguments again since in that case
the caller should continue parsing.

Good catch. It seems this is merely a parsing error, iproute doesn't
have an "action" parameter and aborts parsing, so it uses the default
value of "RECLASSIFY". It never had this parameter, so this patch
removes it from the help text and makes it return an error.

Output from /proc may include partial records, so rather than
trying to be sexy and do own parsing, just use stdio.

The problem is that lib_dir is NULL when calling get_target_names.
