[Bug 1317776] [NEW] Ravello's MAC prefix (2c:c2:60) is not violating any scheme, but rather must be handled as if it is a virtual interface

[Boris Figovsky]

Public bug reported:

The MAC prefix 2c:c2:60 should be treated like 52:54:00 (KVM) and 00:0c:29 VMWare (VMWare):
network devices with a MAC that starts with 2c:c2:60 shall not be persistent.

This MAC prefix belongs to Ravello Systems:

http://www.ravellosystems.com

According to /lib/udev/rules.d/75-persistent-net-generator.rules of
version 204-5ubuntu20, this MAC prefix is in the list of the local MAC
address assignment scheme violators, but in fact this MAC always belongs
to a virtual interface, such as KVM, VirtualBox and VMWare.

This bug affects Ubuntu Trusty.
(Ubuntu Precise had this bug as well, and already fixed: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1099278).

An upstream patch is attached.
