Summary

0005642: TS102636-6-1 v0.0.7 section 8: not enough clarity on the Ethernet header generation for received messages

Description

Based on various other sections, the following assumptions are made for message reception over a TAP virtual device, which should be clearly stated in the relevant paragraph of section 8:
- the IPv6overGeoNetworking adaptation generates the Ethernet headers for the received IPv6 message
- the Source MAC address is generated through reverse EUI-64 generation procedure from the Sending GN_Address
- the Destination MAC address is set to the Ethernet broadcast address for Multicast/Anycast message types
- the Destination MAC address is generated through reverse EUI-64 generation procedure from the Destination GN_Address for Unicast message types
- the Ethertype is set to IPv6 or ICMPv6 according to received message type

Please confirm these assumptions, as some test cases are based on the above.

Notes
(0009729) Roberto Baldessari (developer) 08-09-2010 17:54	Issue 0005642 resolved in v0.0.8 by adding annex D.2 "Packet delivery with Ethernet V2.0/IEEE 802.3 LAN virtual interfaces" which explains the steps undertaken by an implementation using Ethernet virtual interfaces. Please note that the operations of the virtual interfaces are implementation-specific and they can only be recommended in an informative annex. Section 8 (and the whole doc) defines logical operations based on SAPs and in an virtual interface type-independent way. e.g.: using Ethernet VI and creating Ethernet frames to be passed up/down is a way to implement the SAP
