The main steps in setting up a network adapter are:
identifying your Network Interface Card (NIC)
starting the driver
making sure the driver and hardware communicate
Identify your NIC
The documentation for the hardware should describe the type of chipset used.
Start the driver
Once you've located the correct driver for your hardware, use io-pkt* to start the driver. You can either start the driver as an option to io-pkt*, or you can mount the driver into an already running copy of io-pkt*.
