/**

 * @{ 2003-10-01 draft-ietf-eap-rfc2284bis-06.txt chapter 2.1 Support for sequences:

 * An EAP conversation MAY utilize a sequence of methods.  A common

 * example of this is an Identity request followed by a single EAP

 * authentication method such as an MD5-Challenge.  However the peer and

 * authenticator MUST utilize only one authentication method (Type 4 or

 * greater) within an EAP conversation, after which the authenticator

 * MUST send a Success or Failure packet.

 * Once a peer has sent a Response of the same Type as the initial

 * Request, an authenticator MUST NOT send a Request of a different Type

 * prior to completion of the final round of a given method (with the

 * exception of a Notification-Request) and MUST NOT send a Request for

 * an additional method of any Type after completion of the initial

 * authentication method; a peer receiving such Requests MUST treat them

 * as invalid, and silently discard them. As a result, Identity Requery

 * is not supported.

 * A peer MUST NOT send a Nak (legacy or expanded) in reply to a

 * Request, after an initial non-Nak Response has been sent.  Since

 * spoofed EAP Request packets may be sent by an attacker, an

 * authenticator receiving an unexpected Nak SHOULD discard it and log

 * the event.

 * Multiple authentication methods within an EAP conversation are not

 * supported due to their vulnerability to man-in-the-middle attacks

 * (see Section 7.4) and incompatibility with existing implementations.

 * }
