The patch adds support for configuring the erspan v2, for both ipv4 and ipv6 erspan implementation. Three additional fields are added: 'erspan_ver' for distinguishing v1 or v2, 'erspan_dir' for specifying direction of the mirrored traffic, and 'erspan_hwid' for users to set ERSPAN engine ID within a system. As for manpage, the ERSPAN descriptions used to be under GRE, IPIP, SIT Type paragraph. Since IP6GRE/IP6GRETAP also supports ERSPAN, the patch removes the old one, creates a separate ERSPAN paragrah, and adds an example.
