Driver Parameters

NetQueue

The optional parameter force_netq can be used to set the number of Rx and Tx net queues. BCM57XX devices that support
NetQueue are the BCM5718, BCM5719, BCM5720, BCM5721, and BCM5722.

By default, the driver tries to use the optimal number of NetQueues. To explicitly force the number of queues, set the number
of NetQueues per port via the following command:

esxcfg-module -s force_netq=x,x,x.... tg3

Allowed values for x are –1 to 15:

1–15 will force the number of NetQueues for the given NIC.
0 disables NetQueue.
–1 specifies to use the default driver NetQueue value.

the number of "x" entries can go up to 32, which means the maximum supported NICs = 32.

Example usage:

esxcfg-module -s force_netq=-1,0,1,2 tg3]

tg3 NIC 0: Use the default number of NetQueues.
tg3 NIC 1: Disable the NetQueue feature.
tg3 NIC 2: Use 1 NetQueue.
tg3 NIC 3: Use 2 NetQueues.

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
