Yes, we configure it with rte_eth_dev_filter_ctrl() and with
RTE_ETH_FILTER_FDIR filter type.  With Chelsio hardware it's possible
to match several different filters in the same rule.

For e.g., it's possible to set a vlan, ethertype, and n-tuple filters
all on the same rule.

The generic architecture [1] for flow director can accept these several
filters in the same rule and hence the cxgbe flow director can handle
these different filters with this generic approach.
