Hi DPDK community, I've been using DPDK v1.7 and v1.8 for the past year. On updating to v2.0.0, I see that *rte_5tuple_filter* has been deprecated as well as the associated install/remove call,* rte_eth_dev_add_5tuple_filter()*
I now see that rte_eth_ntuple_filter has been added in place. 1) Is there a specific reason for removing backward compatibility? As in is there a known issue with rte_5tuple_filter infra that was discovered in v2.0? 2) One limitation of rte_5tuple_filter was that it could not be used to filter /24 or /16 ip addresses(subnet filtering). I now see that the src_ip_mask and dst_ip_mask is 32 bits and a separate RTE_NTUPLE_FLAGS_SRC_IP <http://dpdk.org/doc/api/rte__eth__ctrl_8h.html#aff1204ca0b33628610956f840dd9b206> has been introduced. Does this imply that we NOW support subnet filtering(use mask for wildcard masking)? Any help or pointers on the subject will be greatly appreciated!!! Thanks, Kam
