Document Table of Contents Latency Tolerance Reporting (LTR)

This capability allows the F-Tile Avalon streaming IP, when operating in Endpoint mode, to report the delay that it can tolerate when requesting service from the Host. This information can help software optimize performance when the Endpoint needs a fast response, or optimize system power when a fast response is not necessary.
