Why not add a 32-bit field to the skb to handle various flag needs
going forward?

If space is very important, could use an uint16 for flags and consolidate
the ip_summed and cloned fields, which seem to be boolean fields.

        unsigned char           local_df,
                                cloned,
                                pkt_type,
                                ip_summed;
