Installing the NIC Driver

Note: The following command can be used to get the value:
#esxcli network nic list
The output should look similar to the following:
Virtualization Support
For the best performance, you must install VMware Tools in each guest operating
system. For information on installing VMware Tools in a Linux or Windows guest
operating system, refer to the appropriate VMware ESXi Server documentation.
NetQueue Support
NetQueue enables support for multiple transmit and receive rings for improved
performance. NetQueue is enabled by default.

To determine whether NetQueue is enabled, run the following command from
the ESXi Server console:
# esxcfg-advcfg -j netNetqueueEnabled
If it returns 'netNetqueueEnabled = FALSE', NetQueue is disabled.

To enable NetQueue, run the following command:
# esxcfg-advcfg -k TRUE netNetqueueEnabled
Reboot the ESXi Server for the change to take effect.
How an ESXi Server Creates and Names Interfaces
The NIC driver supports a maximum of four adapters per system. For dual-channel
adapters running in standard operating mode, the driver creates two interfaces (one for
each physical port). The first and second interfaces are respectively named vmnic0 and
vmnic1 (assuming there are no other network interfaces in your configuration). The
same applies to vNIC-capable adapters when vNIC mode is disabled in the adapter
BIOS (for those boards that support vNIC).
When vNIC mode is enabled in the adapter BIOS and the adapter is in NIC-only mode,
the driver creates eight interfaces (four for each physical port). The interfaces are
labeled vmnic0 through vmnic7 (assuming there are no other network interfaces in
your configuration).
Note: When vNIC mode is enabled in the adapter BIOS and the adapter is in FCoE or
iSCSI mode, the driver creates only six NIC interfaces. The other two interfaces
are reserved for FCoE and iSCSI.
