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.
