-/**
- * 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.

+ * 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.
