[Bug 1281366] Re: ip command becomes slower with large number of network devices

[Ian! D. Allen]

Ubuntu 12.04.4 LTS  3.8.0-36-generic #52~precise1-Ubuntu SMP Mon Feb 3

I just said "this bug affects me too", but what I really meant to say
was "the fix is broken for me too" and shows "if" numbers instead of
interface device names.  I had to downgrade back to the previous
version.

Bug description:
  [Impact]
  When using iproute commands with a large number of network devices (virtual ethernet adapters, etc) iproute performance becomes much slower.

  [Test Case]
  1) Download attached 'make_fake_routers.sh' and 'parse.py' scripts.
  2) ./make_fake_routers.sh 3000 ip > results
  3) ./parse.py results

  You should be able to graph and clearly see a performance improvement
  with the fix than without it.
