* NOTE! NOTE! NOTE!
|
|
*
|
|
* Bluetooth specification says that L2CA_xxx request must block until

|
* response is ready. We are not allowed to block in Netgraph, so we
|
|
* need to queue request and save some information that can be used
|
|
* 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.
|
|
*
|

* NOTE: This is _NOT_ what NG_MKRESPONSE and NG_RESPOND_MSG do, however
