SRIO Functional Description
The type of received packet determines how the packet routing is handled. Reserved or undefined packet
types are destroyed before being processed by the logical layer functional blocks. This prevents erroneous
allocation of resources to them. Unsupported packet types are responded to with an error response
packet. Section 2.1.2.4 details the handling of such packets.
2.1.2.4 SRIO Packet Ftype/Ttype
The type of SRIO packet is determined by the combination of Ftype and Ttype fields in the packet. Table 2
lists all supported combinations of Ftype/Ttype and the corresponding decoded actions on the packets.
