I just have to make IP happen over a wireless link device (which is
still a protype or does not event exist) that claims to be
802.15.3. The API's provided are almost straight from the IEEE
standard in format
MA-UNITDATA.request (
SourceAddress,
DestinationAddress,
RoutingInformation,
Data,
Priority,
ServiceClass
)
Note, the obnoxious "Priority" and "ServiceClass" *after* the variable
length data, seemed ridiculous layout (and may cause need to copy data in
linux driver to expand sk_buff for them for each packet... yechh!)
Of course, this is internal, not on the wire format. For the wire I
would need to know how to put the additional require "EtherType" into
payload. I seem to have two choices
1) 802.15.3b way, use 8 first octets of the payload for LLC/SNAP
2) ECMA-368 (Annex A.1 MUX service), use 2 first octets of the
payload for EtherType.
To me, ECMA way seems much more compact, but of course, if someone
else is doing link layer for this 15.3, would prefer to use the same
payload format. That's why I was asking around for opinions...
