33 | * RX PATH | ||
34 | * | ||
35 | * The Rx path uses a double buffer and an rx_contro structure, each located | ||
36 | * at a fixed address in the device memory. The host keeps track of which | ||
37 | * buffer is available and alternates between them on a per packet basis. | ||
38 | * The size of each of the two buffers is large enough to hold the longest | ||
39 | * 802.3 packet. | ||
40 | * The RX path goes like that: | ||
41 | * 1) The target generates an interrupt each time a new packet is received. | ||
42 | * There are 2 RX interrupts, one for each buffer. | ||
43 | * 2) The host reads the received packet from one of the double buffers. | ||
44 | * 3) The host triggers a target interrupt. | ||
45 | * 4) The target prepares the next RX packet. | ||
