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.

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.
