In NAVSS0, a total of 140 Rx channels are provided within the DMA for concurrent transfers between the Rx Per Channel Buffers and memory mapped space. Each of these channels can be configured to operate as a packet oriented channel (uses rings/descriptors/buffer) or as a Third Party DMA destination channel (uses rings/Transfer Request packets or TR standalone records to control read operations). Depending on which channel mode is selected, when a Tx channel comes into context the work for that channel will either be dispatched to an Rx Packet DMA Unit or a Third Party Write Unit respectively. The Rx channels are allocated as shown in Table 10-108.
