I see filter info consist of different filter types, but as far as I can
see they are not used before this memset, so what is the problem of
cleaning all struct?
Currently memset a sub-set of struct, and assigns zero to other field
explicitly, and rest remains undefined and unused. I am suggesting
memset whole structure and get rid of zero assignment.
