struct xhci_ep_ctx : endpoint state, streams, mult, and interval information. : information on endpoint type, max packet size, max burst size, error count, and whether the HC will force an event for all transactions. : 64-bit ring dequeue pointer address. If the endpoint only defines one stream, this points to the endpoint transfer ring. Otherwise, it points to a stream context array, which has a ring pointer for each flow. : Average TRB lengths for the endpoint ring and max payload within an Endpoint Service Interval Time (ESIT).
Endpoint Context - section 6.2.1.2. This assumes the HC uses 32-byte context structures. If the HC uses 64-byte contexts, there is an additional 32 bytes reserved at the end of the endpoint context for HC internal use.
