Network_Interface_Identifier Protocol - Intel Extensible Firmware Interface Specification

Extensible Firmware Interface Specification

15.2 NETWORK_INTERFACE_IDENTIFIER Protocol

Summary
This is an optional protocol that is used to describe details about the software layer that is used to
produce the Simple Network Protocol. This protocol is only required if the underlying network
interface is 16-bit UNDI, 32/64-bit S/W UNDI, or H/W UNDI. It is used to obtain type and
revision information about the underlying network interface.
An instance of the Network Interface Identifier protocol must be created for each physical external
network interface that is controlled by the !PXE structure. The !PXE structure is defined in the
32/64-bit UNDI Specification in Appendix G.

The revision of the
EFI_NETWORK_INTERFACE_IDENTIFIER
protocol.
Address of the first byte of the identifying structure for this network
interface. This is only valid when the network interface is started (see
EFI_SIMPLE_NETWORK_PROTOCOL.Start()). When the network
interface is not started, this field is set to zero.
