/*
|
|
* From Rink Springer @ FreeBSD:
|
|
*
|
|
* Some XBOX loaders, such as Cromwell, have a flaw which cause the
|
|
* nfe(4) driver to fail attaching to the NIC.
|
|
*
|
|
* This is because they leave the NIC running; this will cause the
|
|
* Nvidia driver to fail as the NIC does not return any sensible
|
|
* values and thus fails attaching (using an error 0x5, this means
|
|
* it cannot find a valid PHY)
|
|
*
|
|
* We bluntly tell the NIC to stop whatever it's doing; this makes
|
|
* nfe(4) attach correctly. As the NIC always resides at
|
|
* 0xfef00000-0xfef003ff on an XBOX, we simply hardcode this address.
