[E1000-devel] e1000e and the 2009 Mac Pro

 I am trying to get Linux up and running on my new (2009) Mac Pro (the
4,1 model). I currently have Ubuntu Jaunty (Alpha 6) installed, and amy
working to get the Gig-E interfaces working. It looks like they should
be supported by the e1000e module, but the PCI ID's (8086:10f6) are not
recognized.
 Using ioreg in OS X shows me that both interfaces are recognized as
Intel 82574L's, but lspci in Linux just lists them as:
09:00.0: Ethernet Controller: Intel Corporation Device 10f6
0a:00.0: Ethernet Controller: Intel Corporation Device 10f6
 I was hoping I could simply add this ID to the e1000e driver, and they
would work, but so far, no such luck.
 Working with the e1000e-0.5.18.3 source package off sf.net, I added a
define for the 10F6 ID to hw.h, and a new PCI_VDEVICE line with the
define, and board_ich10lan to netdev.c. It compiled fine, but on loading
I get: The NVM Checksum Is Not Valid. Rebooting to OS X, the interfaces
still work fine. The output from dmesg is:

This is with kernel 2.6.28-11-server (Ubuntu). The Mac Pro is the 8-core
variant (two Xeon E5520's), with the X58 (Tylersburg) chipset.
Any suggestions on where to go next?
 Thanks,
 Doug
