Subject: Mellanox mlx4_en update

I am having trouble getting the mlx4_en driver to work on 3.0.1 kernels.  On 
the advice of Yevgeny, I have pulled patches from net-next and applied them to 
a 3.0.1 stable tree which compiles and runs just fine except for the driver.  
What I know so far:

* The driver in the mlnx_en-1.5.6.tgz tarball from the Mellanox download site 
works just fine with Fedora 12/RHEL6 and earlier kernels.

* Mainline and stable + patches don't on 3.0.1.  See commands and logs below.

* A diff between the two (~15k lines) shows significant differences (mlx4_en is a 
newer version, 1.5.6)

* udev seems to want to install mlx4_core alone but removing and re-installing 
via modprobe of mlx4_en does the loading properly but the driver doesn't init 
properly as shown in the logs.

See the end of the log for a git log short of the patches on top of 3.0.1.

post-boot, the driver had not fully loaded so I removed the only module that 
did load.  I did not show the boot time dmesg but it is identical to the first 
part in the modprobe install log below.

The base install is Fedora 12 with updates on an x86_64 Westmere class server.  
Everything minus 10Ge worked for extensive internal testing.

Am I missing patches?  Might the firmware be out of date?  Note that it works 
w/ F12|RHEL[4-6].

If I can get working patches/firmware/??? I can repackage kernel RPMs so our 
lab folks can deploy this.

Thanks

Jim
