in ipv6 flowspec, a new type is defined to be able to do filtering rules based on 20 bits flow label field as depicted in [0]. The change include the decoding by flowspec, and the addition of a new attribute in policy routing rule, so that the data is ready to be sent to zebra. The commit also includes a check on fragment option, since dont fragment bit does not exist in ipv6, the value should always be set to 0, otherwise the flowspec rule becomes invalid.
