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.
