Abstract
A host station and a scatter gather engine (SGE) station communicate with each other. In the host station, a host generation indication is maintained. In the SGE station, an SGE generation indication is maintained. Information, including the host generation indication maintained in the host station, is written into an entry of a data structure in a memory associated with the host station. In the SGE station, information is received from each of at least one of the entries of the data structure. The received information is processed, including comparing the SGE generation indication maintained in the SGE station to the host generation indication in the entry to determine whether the information in that entry includes valid information.
