The MIU extension value can be received during the PAX or during the
connection establishment process. It's definitely a connection related value
rather than a link one.

RW can only be fetched from a CONNECT or a CC frame thus making it an
end points specific value, not a link one.

After testing our stack with large SNEP messages, we realized the fragments
were arriving in reversed order.

We just don't do anything with it when parsing the general bytes.
We handle it from the CONNECT reception code.

Based on the receiver MIU, we have to fragment the frame to be
transmitted.

In order to acknowledge an I frame, we have to either queue pending local
I frames or queue a receiver ready frame.

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.
