  EFI EAP(Extended Authenticaton Protocol) Protocol Definition\r
  The EFI EAP Protocol is used to abstract the ability to configure and extend the\r
  EAP framework. \r
  The definitions in this file are defined in UEFI Specification 2.3.1B, which have\r
  not been verified by one implementation yet.\r
