Say Y, if you need ath9k to display debug messages.
Pass the debug mask as a module parameter:
Say Y, if you need access to ath9k's statistics for

Also required for changing debug message flags at run time.

* ath9k_hw_updatetxtriglevel - adjusts the frame trigger level
*
* @ah: atheros hardware struct
* @bIncTrigLevel: whether or not the frame trigger level should be updated
*
* The frame trigger level specifies the minimum number of bytes,
* in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
* before the PCU will initiate sending the frame on the air. This can
* mean we initiate transmit before a full frame is on the PCU TX FIFO.
* Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
* first)
*
* Caution must be taken to ensure to set the frame trigger level based
* on the DMA request size. For example if the DMA request size is set to
* 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
* there need to be enough space in the tx FIFO for the requested transfer
* size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
* the threshold to a value beyond 6, then the transmit will hang.
*
* Current dual stream devices have a PCU TX FIFO size of 8 KB.
* Current single stream devices have a PCU TX FIFO size of 4 KB, however,
* there is a hardware issue which forces us to use 2 KB instead so the
* frame trigger level must not exceed 2 KB for these chipsets.
