Overview

========

This driver implements networking functionality of Marvell's Octeon PCI

EndPoint NIC.



Supported Devices

=================

Currently, this driver support following devices:

 * Network controller: Cavium, Inc. Device b200



Interface Control

=================

Network Interface control like changing mtu, link speed, link down/up are

done by writing command to mailbox command queue, a mailbox interface

implemented through a reserved region in BAR4.

This driver writes the commands into the mailbox and the firmware on the

Octeon device processes them. The firmware also sends unsolicited notifications

to driver for events suchs as link change, through notification queue

implemented as part of mailbox interface.
