* later and help match request and response.
|
|
*
|
|
* The idea is to use "token" field from Netgraph message header. The

|
* upper layer protocol _MUST_ populate "token". L2CAP will queue request
|
|
* (using L2CAP command descriptor) and start processing. Later, when
|
|
* response is ready or timeout has occur L2CAP layer will create new
|
|
* Netgraph message, set "token" and RESP flag and send the message to
|
|
* the upper layer protocol.
|
|
*
|
|
* L2CA_xxx_Ind messages _WILL_NOT_ populate "token" and _WILL_NOT_
|
|
* set RESP flag. There is no reason for this, because they are just
|
|
* notifications and do not require acknowlegment.
