Comment 8 for bug 1308036

This problem was caused because ohai has a broken regex (see ohai bug in the commit message). What happens is that when you have an interface like eth10 ohai sets the type to "eth1" instead of "eth". The agent was skipping all interfaces != "eth". This change works around the issue by only skipping interfaces that don't start with "eth". This way interfaces with type |eth1", or "eth2" or whatever won't be skipped.
