+++ This bug was initially created as a clone of Bug #492199 +++
Description of problem:
doing an ifdown on an interface using the below nic does not work properly:
80:0a.0 Ethernet controller: nVidia Corporation CK804 Ethernet Controller (rev f3)
The customer noticed this problem when he switched down one of the interfaces in a bond (using ifconfig ethX down). The IP address is deassigned from the interface, but the link is up and the kernel keeps using this interface as the current active one in the bond. As the result, the connectivity via the bond interface is lost.
The customer has also reproduced the problem w/out bonding being involved.
Steps to Reproduce:
1. ifdown ethX
physical link remains
interface/link shutdown completely

re-add power down phy patch

additional note: the attached patches were created against kernel-2.6.18-162.el5
