* Trace received messages from user space
*
* In order to tap the bidirectional message stream in the
* 'msg' pipe, user space can read from the 'msg' pipe;
* however, due to limitations in libnl, we can't know what
* the different applications are sending down to the kernel.
*
* So we have this hack where the driver will echo any message
* received on the msg pipe from user space [through a call to
* wimax_dev->op_msg_from_user() into
* i2400m_op_msg_from_user()] into the 'trace' pipe that this
* driver creates.
*
* So then, reading from both the 'trace' and 'msg' pipes in
* user space will provide a full dump of the traffic.
*
* Write 1 to activate, 0 to clear.
*
* It is not really very atomic, but it is also not too
* critical.
