-== VPP to IETF-ACL model translation
-
-Package provides VPP translation code for draft-ietf-netmod-acl-model-08.
-Access control lists are mapped to chains of classify tables, each with single classify session.
-
-=== Available operations
-
-==== Configuration data
-Configuration data for the model is stored in Honeycomb. Corresponding classify tables and sessions
-are not created until control access list is assigned to an interface.
-
-Classify tables and sessions are removed from VPP when ACL assignment is deleted.
-
-ACLs can be shared among interfaces, but each time, new instance of classify table chain would be created in VPP.
-
-ACLs that are assigned to an interface have to be unassigned before update/removal.
-
-==== Operational state
-Operational read in terms of ietf-acl model is not supported (would require storing additional metadata in vpp).
-As a consequence, configuration data initialization based on operational state is not possible.
-
-To check how ietf-acl model was translated to classify tables/session, low-level vpp-classfier model can be used.
-
-=== Restrictions
-
-VPP classfier works in form of offsets and masks of 16B units.
-The offset always starts at the beginning of L2 Ethernet header
-of input packet. Because IP header can have variable length,
-source/destination port matching (L4 features of ietf-acl model) is not possible. \ No newline at end of file
