/*
* 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
* it is somewhat similar.
