Name (Pointer 0)

Human-readable null-terminated string name for this interface.

Ethernet MAC Address (Pointer 1)

The 48-bit Ethernet MAC address.

Typically a unique static value assigned during manufacture from a block of MAC addresses assigned to the manufacurer by the IEEE.

IP Address (Pointer 2)

IPv4 address used by the interface (may be 0 if uninitialized).

Static IP Address (Pointer 3)

The user assigned IPv4 address used to be used by the interface.

If set to 0 or not implemented, another method is required to assign the operating device IP address.

Subnet Mask (Pointer 4)

32-bit IPv4 subnet mask.

Static Subnet Mask (Pointer 5)

The user assigned 32-bit IPv4 subnet mask.

If set to 0 or not implemented, another method may be required to assign the operating device Subnet Mask.

Gateway Address (Pointer 6)

32-bit Ethernet gateway address.

Static Gateway Address (Pointer 7)

The user assigned 32-bit Ethernet gateway address.

If set to 0 or not implemented, another method may be required to assign the operating device Ethernet gateway address.

Ethernet PHY Feature (0x102)

The Ethernet PHY Feature offers pointers to values describing and controlling one Ethernet PHY connected to the device. Multiple Ethernet PHY features may be implemented.

Packet Resend Feature (0x104)

EEVideo devices may implement functionality to retransmit video stream packets that were lost or damaged. The host requests retransmission using the registers pointed to by this feature.

The device must maintain memory buffers long enough for the host to request retransmission.
