Under this logic, we can use the values and not the masks, isn't that?

No, it's perfectly valid to specify a filter that matches, for example,
a destination IP address of 0.0.0.0 with mask of 255.255.255.255.  So
you really need to check the mask.  If your filter hardware doesn't
support zero values for some fields then you'll need to reject them in
mlx4_en_validate_flow.

Got it, will change to use masks all over the place, as you pointed out 
we need to do.
