NetXtreme User Guide
Note that the NIC # above does not correspond to the vmnic<#>. The NIC number is the system vmnic probe
order number. Optimally, the number of NetQueues matches the number of CPUs on the machine.

Driver Parameters

Several optional parameters can be supplied as a command line argument to the vmkload_mod command.
These parameters can also be set via the esxcfg-module command. See the man page for more information.

Driver Messages

The following are the most common sample messages that may be logged in the file /var/log/messages. Use
to control the level at which messages will appear on the console. Most systems are set to
