The default remains at 10 for backwards compatibility.
For instance:
# ip addr flush dev eth2
*** Flush remains incomplete after 10 rounds. ***
# ip -l 20 addr flush dev eth2
*** Flush remains incomplete after 20 rounds. ***
# ip -loops 0 addr flush dev eth2
#
This is useful for getting rid of large numbers of IP
addresses in scripts.

It uses 1MB as receive buf limit by default (without
increasing /proc/sys/net/core/rmem_max it will be limited by less
however) and allows to specify the size manually using "-rcvbuf X"
(-r is already used, so you need to specify at least -rc).
Additionally rtnl_listen() continues on ENOBUFS after printing the
error message.
Add support for using netlink for link configuration. Kernel-support is
probed, when not available it falls back to using ioctls.

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).
