/*
 * bgp_vty_find_and_parse_afi_safi_bgp
 *
 * For a given 'show ...' command, correctly parse the afi/safi/bgp out from it
 * This function *assumes* that the calling function pre-sets the afi/safi/bgp
 * to appropriate values for the calling function.  This is to allow the
 * calling function to make decisions appropriate for the show command
 * that is being parsed.
 *
 * The show commands are generally of the form:
 * "show [ip] bgp [<view|vrf> VIEWVRFNAME] [<ipv4|ipv6>
 * [<unicast|multicast|vpn|labeled-unicast>]] ..."
 *
 * Since we use argv_find if the show command in particular doesn't have:
 * [ip]
 * [<view|vrf> VIEWVRFNAME]
 * [<ipv4|ipv6> [<unicast|multicast|vpn|labeled-unicast>]]
 * The command parsing should still be ok.
 *
 * vty  -> The vty for the command so we can output some useful data in
 *         the event of a parse error in the vrf.
 * argv -> The command tokens
 * argc -> How many command tokens we have
 * idx  -> The current place in the command, generally should be 0 for this
 * function
 * afi  -> The parsed afi if it was included in the show command, returned here
 * safi -> The parsed safi if it was included in the show command, returned here
 * bgp  -> Pointer to the bgp data structure we need to fill in.
 * use_json -> json is configured or not
 *
 * The function returns the correct location in the parse tree for the
 * last token found.
 *
 * Returns 0 for failure to parse correctly, else the idx position of where
 * it found the last token.
