If we use default configuration on HW, this issue will not exist. But
our software sets the default value through i40e_filter_input_set_init.
So I think fix line need to be the commit which introduced input set
changing feature.

Acked-by: Jingjing Wu <jingjing.wu at intel.com> with additional line:

Fixes: commit 98f055707685 ("i40e: configure input fields for RSS or flow director ")


Thanks
Jingjing
