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.
