>>>>>>> Abstract: In order to transmit IPv6 packets on IEEE 802.11
>>>>>>> networks
>>>>>>>> running outside the context of a basic service set (OCB, earlier
>>>>>>>> "802.11p") there is a need to define a few parameters such as
>>>>>>>> the supported Maximum Transmission Unit size on the 802.11-OCB
>>>>>>>> link, the header format preceding the IPv6 header, the Type value
>>>>>>>> within it, and others.  This document describes these parameters
>>>>>>>> for IPv6 and IEEE 802.11-OCB networks; it portrays the layering
>>>>>>>> of IPv6 on 802.11-OCB similarly to other known 802.11 and
>>>>>>>> Ethernet layers - by using an Ethernet Adaptation Layer.
