ESXI 5.0 Using Direct IO for igb, e1000 and bnx drivers

[FedericoAlves]

I was googling about the subject, and found this interesting data about how to use Direct IO:

http://www.extremenetworks.com/libraries/solutions/ANDAVMwareESX_1745.pdf

Please read an exerpt:

"2.1. 2.2.

SSH into the ESX server and login with root privileges.

Setup the driver to operate with 8 functions (func_ mode=1) and disable L2 forwarding in the EXAR Neterion adapter (L2_switch=0).

2.2.1.     Unload the vxge driver.

vmkload-mod –u vxge

2.2.2.     Load the module with the preferred modes for para-virtual.

vmkload-mod vxge l2_switch=0 func_mode=1"

The question is: Is there a comparable change in parameters like the above "vmkload-mod vxge l2_switch=0 func_mode=1" for the drivers igb, e1000 and bnx? If there are, in fact, how do I make those changes permanent?

I am trying to assign a network card directly to Linux virtual machine, Red Hat 6.3, 64. Also, I am trying to assign an SSD directly to a Linux VM. The SSD is part of a PCI SSD solution from OCZ. Has anybody done this? The Vmware version that I am playing with, not in production, is 5.1. I cannot get the same performance that I get in KVM, but maybe I don't have enough information as how to achieve that.
