Hi Thomas,

Got a couple of questions on how to mark some of the features for CXGBE
below.

It is possible to set some of the above filters via our cxgbe flow
director. Do we mark these filter features as supported?

How do you configure these filters? rte_eth_dev_filter_ctrl()?
Which type in rte_filter_type?

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.
