You are correct, my reading of the manpage suggested that per interface
stats should be available.

netstat -i | -I interface -s [-f protocol_family | -p protocol] [-M core]
             [-N system]
             Display per-interface statistics for each network protocol, for a
             particular protocol_family, or for a single protocol.

As that was incorrect then I do consider the manpage to need updating. I'll file a PR but I wasnt sure if this was correct behavior or not.
