I work with IBM HS23 Blade Server (7875). It's onboard NIC adapter is:

   Emulex OCl11104-F-X Virtual Fabric Adapter 2-port 10GB and 2-port 1GB LOM .

I'm tryed to the following Linux OS with the server:

2.6.32-22-generic-pae #36-Ubuntu SMP. 

and discovered my OS has not proper Network drive installed (for the NIC adapter described above). After investigation I made, I discovered that the driver I need is "be2net" placed in "net" directory of the linux under the folder "be2net". I managed to download this driver with the latest package for my kernel. Driver info ("modinfo be2net" result) is as follows:

After starting linux, I get the following error:

be2net 0000:16:00.x: Emulex OneConnect 10Gbps NIC (be3) initilization failed. 

I checked the same server with another Linux version (Red-Had 5.5.1.0) and the NICs worked properly, so seems there is no problem in HW.

Also, on IBM or Emulex offical sites I managed to find drivers only for Red-Had and SUSE versions.
