Data fields.

The client and the network access device uses
EAP-Packets to transport authentication information.
0x01 EAPOL-Start
The client sends an EAPOL-Start message to initiate
802.1X authentication to the network access device.
0x02 EAPOL-Logoff
The client sends an EAPOL-Logoff message to tell the
network access device that it is logging off.
 Length: Data length in bytes, or length of the Packet body. If packet type is EAPOL-Start or
EAPOL-Logoff, this field is set to 0, and no Packet body field follows.
