309  * NOTE! NOTE! NOTE!
310  *
311  * Bluetooth specification says that L2CA_xxx request must block until

313  * need to queue request and save some information that can be used
314  * later and help match request and response.
315  *
316  * The idea is to use "token" field from Netgraph message header. The
317  * upper layer protocol _MUST_ populate "token". L2CAP will queue request
318  * (using L2CAP command descriptor) and start processing. Later, when
319  * response is ready or timeout has occur L2CAP layer will create new
320  * Netgraph message, set "token" and RESP flag and send the message to
321  * the upper layer protocol.
322  *
323  * L2CA_xxx_Ind messages _WILL_NOT_ populate "token" and _WILL_NOT_
324  * set RESP flag. There is no reason for this, because they are just
325  * notifications and do not require acknowlegment.
