> The TC filter flow mapping override completely skipped the call to
> cake_hash(); however that meant that the internal state was not being
> updated, which ultimately leads to deadlocks in some configurations. Fix
> that by passing the overridden flow ID into cake_hash() instead so it can
> react appropriately.
> In addition, the major number of the class ID can now be set to override
> the host mapping in host isolation mode. If both host and flow are
> overridden (or if the respective modes are disabled), flow dissection and
> hashing will be skipped entirely; otherwise, the hashing will be kept for
> the portions that are not set by the filter.
