306 * NOTE! NOTE! NOTE!
307 *
308 * Bluetooth specification says that L2CA_xxx request must block until
309 * response is ready. We are not allowed to block in Netgraph, so we
310 * need to queue request and save some information that can be used
311 * later and help match request and response.
312 *
313 * The idea is to use "token" field from Netgraph message header. The
314 * upper layer protocol _MUST_ populate "token". L2CAP will queue request
315 * (using L2CAP command descriptor) and start processing. Later, when
316 * response is ready or timeout has occur L2CAP layer will create new
317 * Netgraph message, set "token" and RESP flag and send the message to
318 * the upper layer protocol.
319 *
320 * L2CA_xxx_Ind messages _WILL_NOT_ populate "token" and _WILL_NOT_
321 * set RESP flag. There is no reason for this, because they are just
322 * notifications and do not require acknowlegment.
323 *
324 * NOTE: This is _NOT_ what NG_MKRESPONSE and NG_RESPOND_MSG do, however
325 * it is somewhat similar.

306 * NOTE! NOTE! NOTE!
307 *
308 * Bluetooth specification says that L2CA_xxx request must block until
309 * response is ready. We are not allowed to block in Netgraph, so we
310 * need to queue request and save some information that can be used
311 * later and help match request and response.
312 *
313 * The idea is to use "token" field from Netgraph message header. The
314 * upper layer protocol _MUST_ populate "token". L2CAP will queue request
315 * (using L2CAP command descriptor) and start processing. Later, when
316 * response is ready or timeout has occur L2CAP layer will create new
317 * Netgraph message, set "token" and RESP flag and send the message to
318 * the upper layer protocol.
319 *
320 * L2CA_xxx_Ind messages _WILL_NOT_ populate "token" and _WILL_NOT_
321 * set RESP flag. There is no reason for this, because they are just
322 * notifications and do not require acknowlegment.
323 *
324 * NOTE: This is _NOT_ what NG_MKRESPONSE and NG_RESPOND_MSG do, however
325 * it is somewhat similar.
