This is done because cat etc will call read() repeatedly until EOF is reached (or read() returns 0), which in the current implementation will cause said function to be invoked multiple times. With the current implementation this can also cause buggy behavior in some weird edge cases where the first invocation returns a string of length n, and the second of length m>n: The last m-n characters of the second invocation will be printed to screen.

This value is also used for configuring the queue for non-QOS data. However, this tid is used by the FW for management queues. As a result, the FW does not encrypt non-QOS data frames. Fix this by setting the tid for non-QOS data frames to zero, which is a valid value for data frames in the FW. This also fixes a bug in sending multicast frames, where the queues are allocated with tid == 0, but are sent with tid == 8, which may lead to unexpected behavior.

CSA/eCSA IE when relevant 2. If the corresponding probe request had P2P IE, then need to add P2P IE with NOA attributes. However, the NOA attributes and the updated channel switch counter are known only to the FW. The solution is that FW will send a notification with the relevant probe response data and the driver will save it and update the probe response accordingly.

Also, use the STATUS_TRANS_DEAD status bit instead of a bool inside the transport layer. The advantage of this is that now, the transport and the op_mode can know what is the situation and bypass the useless recovery steps mentioned above.

The configuration for these devices should reflect that, but are currently mixed up. To avoid confusion with discrete devices, add part of the firmware to be used and the official name of the device to the cfg structs. This is least reorganization possible (without messing things even more) that could be done as a bugfix for this SoC. Further reorganization of this code will be done separately.
