* rfnoc: Add basic round-robin allocation for linksAlex Williams2019-11-261-12/+65
| | | | | | | | When multiple links are present, the graph_stream_manager will now alternate using them for different streams. It does not consider the required bandwidth of the stream, the channel capacity of the local and remote transport adapters, nor the total reserved capacity of the NIC.
* rfnoc: Add ability to select transport for streamers to user APIsAlex Williams2019-11-261-6/+10
| | | | Now the user can choose which transport is used in connect() calls.
* rfnoc: add rx and tx transports, and amend rfnoc_graphCiro Nishiguchi2019-11-261-0/+34
| | | | | | | | | | | | | | | | | | | | | | | transports: Transports build on I/O service and implements flow control and sequence number checking. The rx streamer subclass extends the streamer implementation to connect it to the rfnoc graph. It receives configuration values from property propagation and configures the streamer accordingly. It also implements the issue_stream_cmd rx_streamer API method. Add implementation of rx streamer creation and method to connect it to an rfnoc block. rfnoc_graph: Cache more connection info, clarify contract Summary of changes: - rfnoc_graph stores more information about static connections at the beginning. Some search algorithms are replaced by simpler lookups. - The contract for connect() was clarified. It is required to call connect, even for static connections.

* rfnoc: Added link/graph specific stream managersAshish Chaudhari2019-11-261-0/+129
- Fleshed out mb_iface - Managers currently only export ctrl APIs. Data APIs TBD
