From: Thomas Monjalon

Since rte_flow is the only API for filtering operations,
the legacy driver interface filter_ctrl was too much complicated
for the simple task of getting the struct rte_flow_ops.

The filter type RTE_ETH_FILTER_GENERIC and
the filter operarion RTE_ETH_FILTER_GET are removed.
The new driver callback flow_ops_get replaces filter_ctrl.
