Hi,
for our new analysis product netANALYZER NG I would like to request a new link-layer type value.

NETANALYZER_NG

The new Link-Layer-Type format is described as following:

Next-generation packet structure:
+---------------------------+
|           Payload         |
.                           .
.                           .
|                           |
+---------------------------+
|           Footer          |
|                           |
+---------------------------+

Next-gen footer description:

[16 bit]  Version            represents current structure version

[8 bit]   SrcIdPart4         source identifier part 3
[64 bit]  VarId              variable identifier
[64 bit]  VarState           variable error states, depending on representation
