Abstract
A method and circuit for implementing variable length packets to embed extra control information in an interconnect system, and a design structure on which the subject circuit resides are provided. Packets are defined to include an End-to-End (ETE) Flow Unit within packet (Flit) count field in the packet header. The packet header also includes its own CRC field. When a nonzero ETE flit count field is received in an incoming packet from an incoming link, the specified number of embedded ETE flits is removed from the packet and is used the same as if the control information arrived in its own packet.
