Increasing efficiency of data payloads to data arrays accessed through registers in a distributed virtual bridge
A system and method for efficient transfer of data in a data from a controlling bridge to a register of a distributed bridge element. A Load Store over Ethernet (LSoE) frame processing engine (FPE) is equipped with a repeat and a repeat with strobe function that, when coupled with an auto-increment function of an indirect register facility, allows a distributed virtual bridge to move data payload more efficiently which decreases the data loading on the computers data paths used for other data transfers.
