NM ignore ethx for testing

[Grant Williamson <traxtopel gmail com>]

Hi,
   I need to do some testing with NetworkManager however I am accessing 
the machine over a VNC connection.
Is there something I can set, so NM will not manage my wired eth0 
connection(i.e. stays up all the time), which will allow me ro test 
eth1(wireless)?

A patch, or edit some lines of code, I am willing to do, anything ...

Yours hopefully.
