Most terms assumed CPU endian, but terms with larger data sizes assumed +big endian (MAC, IPv6 address and custom). + +Term specification was harmonized so that all terms expect value/mask data to be +in big-endian format, have fixed size, and allow free memory alignment. Packet +length term is an exception to this as it does not represent a field in a +packet. + +Added new `ODP_PMR_CUSTOM_L3` term to match custom layer 3 protocol fields. PMR +offset refers to the start of layer 3 in the packet. Other PMR rules (e.g. L2 +classification rules) may precede custom L3 rules. + +=== Helper +Duplicate `ODPH_UNUSED` macro has been removed. `ODP_UNUSED` should be used +instead. + +=== Validation Tests +==== Common +Improved test result output when some tests are inactive (skipped due to missing +capability). Now inactive tests are listed by default in the test suite results. + +==== Classifier +Cleaned up validation test code. Classifier implementation missed reporting some +capabilities, tests didn't check those capabilities and they were tested. Source +IPv4 term test was missing. + +Added serial PMR test, which tests series of PMR and CoS: + +* From default CoS to dest IPv4 CoS +* From dest IPv4 CoS to dest UDP CoS + +Added parallel PMR test, which test serial and parallel PMR and CoS: + +* From default CoS to dest IPv4 CoS +* From dest IPv4 CoS to a parallel UDP CoS per destination port number + +==== Scheduler +Added new validation tests to verify that packet order is maintained when events +are enqueued and dequeued to/from a plain queue while maintaining atomic/ordered +scheduling context. + +==== Timer +Added private timer pool test, which creates a timer pool with the `priv` flag +set. The same thread calls schedule / queue_deq that created the pool. + +=== Example Applications +==== timer_perf +Added new test application to measure schedule call CPU cycle consumption with +various timer pool parameter combinations. This measurement is mostly +interesting with software-based timer implementations, where timers may be +polled from the schedule call. + +==== New odp_ping application +This application replies to IPv4 ping requests. It can be used to test +connectivity with standard ping utility. ARP table needs to be setup manually on +the sender side as the application does not reply to ARP requests. + +==== odp_classifier +Added source CoS name into the parameter list of `-p` option. This enables +linking classification rules together. When a source CoS is not defined, the +default CoS is used as the source CoS. + +Option `-p` parameter list format is now: + + <term>:<xxx>:<yyy>:<src_cos>:<dst_cos> + +Where `<src_cos>` is optional and number of "xxx", "yyy", etc. parameters is +term depend. + +Added `-v` option which prints received packet with CoS queue +name. This can be used for debugging classification rules. + +Added support for `ODP_PMR_VLAN_ID_0`, `ODP_PMR_ETHTYPE_0`, `ODP_PMR_CUSTOM_L3`, +`ODP_PMR_ETHTYPE_X`, `ODP_PMR_VLAN_ID_X`, `ODP_PMR_UDP_DPORT`, +`ODP_PMR_UDP_SPORT`, `ODP_PMR_TCP_DPORT`, and `ODP_PMR_TCP_SPORT` rules. + +==== timer_accuracy +Fix bug in timer start offset calculation. Test results were offset by current +local time value. + +Added delay and extra schedule calls to ensure that (software) timer +implementation has passed its initial state before setting up timers. + +Added `-f` option to control offset to the first timer. This can be used e.g. to +avoid best/worst case synchronization of timers to timer tick boundaries / +resolution. + +==== packet_dump +Added ICMP support. Print ICMP offset and ICMPv4 type/code. This helps to verify +that ping requests are received. + +==== bench_packet +Added missing tests for the following packet functions: + +* `odp_packet_data_seg_len()` +* `odp_packet_free_sp()` +* `odp_packet_from_event_multi()` +* `odp_packet_to_event_multi()` +* `odp_packet_subtype()` +* `odp_packet_parse()` +* `odp_packet_parse_multi()` + +=== Implementation +==== Classifier +Cleaned up implementation. Fixed endianness. + +==== Inline Timer +Cleaned up code. Fixed accuracy issue with high resolution (<100us) timer pools. +Added configuration option `inline_poll_interval_nsec` to select default poll +interval in nsec. + +Added configure file option for inline timer (`inline_thread_type`) to select if +control threads poll shared timer pools or not. Control threads still poll their +private pools. With this user can configure control and worker threads to use +separate timer pools. + +==== Packet I/O +Enable explicit pktio type definition. The pktio type is selected by adding +pktio_type prefix in front of device name separated by a colon +(<pktio_type>:<if_name>). + +The socket mmsg pktio implementation has been refactored and performance has +been improved. + +The IPC pktio implementation has been modified to use standard ODP internal +`ring_ptr_t` rings to implement IPC rings. This enables removing the duplicate +`_ring_t` implementation. + +==== Pool +Packet segmentation has been reimplemented using a linked list. The new +implementation is simpler and has the added benefit of greatly reducing +packet and buffer header sizes. + +=== Bug Fixes +==== Unnumbered Bugs / Issues +* Fixed socket mmap pktio throughput collapse under heavy traffic + +* Fixed missing config header in install directory + +* Include only ODP defines in autogenerated header files + +* Fixed GCC 9 `address-of-packed-member` warnings + +* Disable building static test applications without static ODP lib + +* Fixed a segfault in `odp_pktin_recv_mq_tmo()` implementation + +* Fixed classifier vlan match bugs and tests + +* Fixed classifier matching of parallel PMRs + + == OpenDataPlane (1.22.0.0) === Summary of Changes ODP v1.22.0.0 adds several smaller API changes mainly related to API
