Netqueue on ESxi

Can anybody clarify the use of netqueue and how it works by default?  I understand it is enabled on the host by default but I see no further configuration for the drivers.  I have read everything I can find but am still not clear.  Here is form the Vmware Docs:

Procedure

1. In the ESXi Shell on the host, use the following command:esxcli system settings kernel set --setting="netNetqueueEnabled" --value="TRUE"
2. Use the esxcli module parameters set command to configure the NIC driver to use NetQueue.For example, on a dual-port Emulex NIC run this ESXCLI commands to configure the driver with 8 receive queues    esxcli system module parameters set -m tg3 -p force_netq=8,8

Is there a value for teh second command by default?  What if I were to re enable netqueue and not run the second command above?  Does that mean it is useless? 

ThankYou
