> Add support for parsing TTL and ToS (Hop Limit and Traffic Class) tc fields
> and matching on those fields in filters. Incomplete part of implementation
> was already in place (getting enc_ip and enc_tos from flow_match_ip and
> writing them to filter header).
> 
> Note: matching on ipv6 ip_ttl, enc_ttl and enc_tos is currently not supported
> by the DDP package.

> v3: rebase (update ICE_TC_FLWR_FIELD_*)
> v2: wrap bitops conditions in brackets, use be32p_replace_bits to set
>     TC field in ipv6 header (thanks Alex!)
