EFI EAP Management Protocol Definition
|
|
The EFI EAP Management Protocol is designed to provide ease of management and
|
|
ease of test for EAPOL state machine. It is intended for the supplicant side.
|
|
It conforms to IEEE 802.1x specification.
|
|
The definitions in this file are defined in UEFI Specification 2.2, which have
|
|
not been verified by one implementation yet.
