> 
> In ice_hash_create(), whatever the hash_function is, the filter_ptr->symm is
> always 0 and when we destroy the flow, the ice_rem_rss_cfg() is never carried
> out. So the destroy function never works well. The patch fixes this issue and at
> the same time distinguishes semanteme between simple_xor and
> symmetric_toeplitz.
> 
> To fix this issue, the patch adds a new structure to include a flag to indicate if it
> is a simple_xor flow so that it's easier to remove the config when destroying
> the flow. The patch also simplifies code implementation logic in
> ice_hash_create().
