Cao, Yahui Sept. 6, 2019, noon UTC
Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. Only basic pattern
and queue/passthru/drop are supported.

Add ice_destroy_fdir_filter to destroy a rule. If a flow is created
before, filter rule will be removed from HW.

Only basic patterns and queue/passthru/drop actions are supported?
