I am not disagreeing that iproute2 should handle the extended
error format. Just want the solution to be as small as possible;
ie do no more than is absolutely necessary. And future proof
for the inevitable growth in new area.

This patch makes iproute2 now doing validation of netlink attributes
coming back from the kernel. What is the point, userspace should be
trusting the kernel.
