NetQueue and VMDq are enabled by default in 4.x so you don't
need to enable either of them. Just make sure that you have one of the
following network controllers on your Intel(R) Ethernet 10GbE Server Adapter.
10GbE
Intel® Ethernet Controller 82598
Intel® Ethernet Controller 82599
To verify that VMDq has been successfully enabled:
Verify NetQueue has been enabled: # cat /etc/vmware/esx.conf
Confirm the following line has been added into the file: /vmkernel/netNetqueueEnabled = "TRUE"
Verify the options configured for the ixgbe module: # esxcfg-module -g ixgbe
The output is similar to: ixgbe enabled = 1 options = 'InterruptType=2,2 VMDQ=16,16'
You will see VMDQ=16,16 on a dual port 82598 and VMDQ=64,64 on a dual port 82599.
If VMDQ does not seem to be enabled make sure you have the
latest ixgbe driver and check this kb for more information – kb 1004278.
While the following Intel Ethernet Controllers do support
VMDq in hardware, currently ESX 4 support is being developed and may be added
at a future date.
1GbE
Intel® Ethernet Controller 82575
Intel® Ethernet Controller 82576
Intel® Ethernet Controller 82580
