Description of problem:
It seems impossible to change the MAC using the NetworkManager Applet. Once changed, unable to restart eth0 (Auto Ethernet)

Version-Release number of selected component (if applicable):
0.7.996

How reproducible:
Very

Steps to Reproduce:
1. Right Click NM applet and edit connections
2. Edit your ethernet properties and assign a MAC address, then apply.
3. Re-enabling your ethernet adapter fails.
  
Actual results:
The MAC address should change smoothly..

Expected results:
It dosent...

Additional info:
My analysis:
When the MAC is assigned through NM, an entry HWADDR is made in In /etc/sysconfig/network-scripts/ifcfg-ethX which should actually be MACADDR.. This also results in a SELinux error
