Update Network Drivers on an ESX box
To place the server into maintenance mode
Navigate to the /usr/bin/ directory
Run the following command
Copy the ESX Bundle to a directory on the server, I chose the /sbin/ directory since the esxupdate command also resides there.
Complete this command to install the driver
esxupdate update --bundle <bundle name.zip>
This will complete the driver install, once completed you will want to remove your ESX box from maintenance mode
