John, I believe the matrix is a list of TCP features that are implemented on the router as an end-system and affect only TCP traffic with the router as the src or dst.
1) Socket API - sockets are a network programming application interface. To me this would only be of interest to Cisco code jockeys. 2) SACK - TCP Selective ACKnowledgement. RFC 2018 and RFC 2883. I think most of this would be of interest only to Cisco's own coders. It is interesting to know what versions support FTP and RCP, but the support for socket API's is largely irrelevant unless you need to write code to those sockets.
