Patch 2 extends the ACL handling in \nlibrte_flow_classify to include keys on the properties in \naddition to the tcp 4-tuple.\n\nNote that one particular part of this patch-set where feedback\nis requested is in allocate_acl_ipv4_tcp_5tuple_rule():\nwe need to add a key for the 8 bit flags, but the multibit\ntrie lookup moves in steps of 4 bytes, so it took some hackery\nto figure out what byte-ordering was expected, and there were\nno documentation/examples to provide guidelines.
