+ *
+ * TX PATH
+ *
+ * The Tx path uses a double buffer and a tx_control structure, each located
+ * at a fixed address in the device's memory. On startup, the host retrieves
+ * the pointers to these addresses. A double buffer allows for continuous data
+ * flow towards the device. The host keeps track of which buffer is available
+ * and alternates between these two buffers on a per packet basis.
+ *
+ * The size of each of the two buffers is large enough to hold the longest
+ * 802.3 packet - maximum size Ethernet packet + header + descriptor.
+ * TX complete indication will be received a-synchronously in a TX done cyclic
+ * buffer which is composed of 16 tx_result descriptors structures and is used
+ * in a cyclic manner.
+ *
+ * The TX (HOST) procedure is as follows:
+ * 1. Read the Tx path status, that will give the data_out_count.
+ * 2. goto 1, if not possible.
+ * i.e. if data_in_count - data_out_count >= HwBuffer size (2 for double
+ * buffer).
+ * 3. Copy the packet (preceded by double_buffer_desc), if possible.
+ * i.e. if data_in_count - data_out_count < HwBuffer size (2 for double
+ * buffer).
+ * 4. increment data_in_count.
+ * 5. Inform the firmware by generating a firmware internal interrupt.
+ * 6. FW will increment data_out_count after it reads the buffer.
+ *
+ * The TX Complete procedure:
+ * 1. To get a TX complete indication the host enables the tx_complete flag in
+ * the TX descriptor Structure.
+ * 2. For each packet with a Tx Complete field set, the firmware adds the
+ * transmit results to the cyclic buffer (txDoneRing) and sets both done_1
+ * and done_2 to 1 to indicate driver ownership.
+ * 3. The firmware sends a Tx Complete interrupt to the host to trigger the
+ * host to process the new data. Note: interrupt will be send per packet if
+ * TX complete indication was requested in tx_control or per crossing
+ * aggregation threshold.
+ * 4. After receiving the Tx Complete interrupt, the host reads the
+ * TxDescriptorDone information in a cyclic manner and clears both done_1
+ * and done_2 fields.

- *
- * TX PATH
- *
- * The Tx path uses a double buffer and a tx_control structure, each located
- * at a fixed address in the device's memory. On startup, the host retrieves
- * the pointers to these addresses. A double buffer allows for continuous data
- * flow towards the device. The host keeps track of which buffer is available
- * and alternates between these two buffers on a per packet basis.
- *
- * The size of each of the two buffers is large enough to hold the longest
- * 802.3 packet - maximum size Ethernet packet + header + descriptor.
- * TX complete indication will be received a-synchronously in a TX done cyclic
- * buffer which is composed of 16 tx_result descriptors structures and is used
- * in a cyclic manner.
- *
- * The TX (HOST) procedure is as follows:
- * 1. Read the Tx path status, that will give the data_out_count.
- * 2. goto 1, if not possible.
- * i.e. if data_in_count - data_out_count >= HwBuffer size (2 for double
- * buffer).
- * 3. Copy the packet (preceded by double_buffer_desc), if possible.
- * i.e. if data_in_count - data_out_count < HwBuffer size (2 for double
- * buffer).
- * 4. increment data_in_count.
- * 5. Inform the firmware by generating a firmware internal interrupt.
- * 6. FW will increment data_out_count after it reads the buffer.
- *
- * The TX Complete procedure:
- * 1. To get a TX complete indication the host enables the tx_complete flag in
- * the TX descriptor Structure.
- * 2. For each packet with a Tx Complete field set, the firmware adds the
- * transmit results to the cyclic buffer (txDoneRing) and sets both done_1
- * and done_2 to 1 to indicate driver ownership.
- * 3. The firmware sends a Tx Complete interrupt to the host to trigger the
- * host to process the new data. Note: interrupt will be send per packet if
- * TX complete indication was requested in tx_control or per crossing
- * aggregation threshold.
- * 4. After receiving the Tx Complete interrupt, the host reads the
- * TxDescriptorDone information in a cyclic manner and clears both done_1
- * and done_2 fields.
