The problem space of TCP flow tracking and classification based on TCP state requires the ability to classify TCP flows on more packet properties than just the 4-tuple, e.g., TCP flags. This patch-set provides the set of changes needed in the examples/flow_classify.c needed to achieve this.
Patch 1 extends examples/flow_classify.c to allow constraints on tcp flags. Patch 2 extends the ACL handling in librte_flow_classify to include keys on the properties in addition to the tcp 4-tuple. Sowmini Varadhan (2): Hooks to allow the setting of filters on tcp flags Allow the flow_classify example to add an ACL table for tcp. examples/flow_classify/flow_classify.c | 118 +++++++++++++++++--- examples/flow_classify/ipv4_rules_file.txt | 22 ++-- lib/flow_classify/rte_flow_classify.c | 87 +++++++++++++++ lib/flow_classify/rte_flow_classify.h | 19 ++++ lib/flow_classify/rte_flow_classify_parse.c | 8 +- 5 files changed, 228 insertions(+), 26 deletions(-) -- 2.17.1
