now implemented. Only flow mod and port mod messages are supported
in bundles.
* New OpenFlow extension NXM_NX_MPLS_TTL to provide access to MPLS TTL.
- * New "sampling_port" option for "sample" action to allow sampling
- ingress and egress tunnel metadata with IPFIX.
* New output option, output(port=N,max_len=M), to allow truncating a
packet to size M bytes when outputting to port N.
+ * New command OFPGC_ADD_OR_MOD for OFPT_GROUP_MOD message that adds a
+ new group or modifies an existing groups
+ - Improved OpenFlow version compatibility for actions:
+ * New OpenFlow extension to support the "group" action in OpenFlow 1.0.
+ * OpenFlow 1.0 "enqueue" action now properly translated to OpenFlow 1.1+.
+ * OpenFlow 1.1 "mod_nw_ecn" and OpenFlow 1.1+ "mod_nw_ttl" actions now
+ properly translated to OpenFlow 1.0.
- ovs-ofctl:
* queue-get-config command now allows a queue ID to be specified.
- * '--bundle' option can now be used with OpenFlow 1.3.
+ * '--bundle' option can now be used with OpenFlow 1.3 and with group mods.
+ * New "bundle" command allows executing a mixture of flow and group mods
+ as a single atomic transaction.
* New option "--color" to produce colorized output for some commands.
- * New commands "dump-ipfix-bridge" and "dump-ipfix-flow" to dump bridge
- IPFIX statistics and flow based IPFIX statistics.
+ * New option '--may-create' to use OFPGC_ADD_OR_MOD in mod-group command.
+ - IPFIX:
+ * New "sampling_port" option for "sample" action to allow sampling
+ ingress and egress tunnel metadata with IPFIX.
+ * New ovs-ofctl commands "dump-ipfix-bridge" and "dump-ipfix-flow" to
+ dump bridge IPFIX statistics and flow based IPFIX statistics.
+ * New setting other-config:virtual_obs_id to add an arbitrary string
+ to IPFIX records.
- Linux:
* New QoS type "linux-noop" that prevents Open vSwitch from trying to
manage QoS for a given port (useful when other software manages QoS).
- DPDK:
* New option "n_rxq" for PMD interfaces.
Old 'other_config:n-dpdk-rxqs' is no longer supported.
+ Not supported by vHost interfaces. For them number of rx and tx queues
+ is applied from connected virtio device.
+ * New 'other_config:pmd-rxq-affinity' field for PMD interfaces, that
+ allows to pin port's rx queues to desired cores.
* New appctl command 'dpif-netdev/pmd-rxq-show' to check the port/rxq
assignment.
* Type of log messages from PMD threads changed from INFO to DBG.
* PMD threads servicing vHost User ports can now come from the NUMA
node that device memory is located on if CONFIG_RTE_LIBRTE_VHOST_NUMA
is enabled in DPDK.
+ * Basic connection tracking for the userspace datapath (no ALG,
+ fragmentation or NAT support yet)
+ * Support for DPDK 16.07
+ * Optional support for DPDK pdump enabled.
+ * Jumbo frame support
+ * Remove dpdkvhostcuse port type.
+ - Increase number of registers to 16.
- ovs-benchmark: This utility has been removed due to lack of use and
bitrot.
- ovs-appctl:
* Dropped support for kernel older than 3.10.
* Removed VLAN splinters feature.
* Support for truncate action.
+ * Datapath supports kernel upto 4.6.
- Tunnels:
* Flow based tunnel match and action can be used for IPv6 address using
tun_ipv6_src, tun_ipv6_dst fields.
- * Added support for IPv6 tunnels to native tunneling.
+ * Added support for IPv6 tunnels, for details checkout FAQ.
- A wrapper script, 'ovs-tcpdump', to easily port-mirror an OVS port and
watch with tcpdump
+ - Introduce --no-self-confinement flag that allows daemons to work with
+ sockets outside their run directory.
+ - ovs-pki: Changed message digest algorithm from SHA-1 to SHA-512 because
+ SHA-1 is no longer secure and some operating systems have started to
+ disable it in OpenSSL.
+ - Add 'mtu_request' column to the Interface table. It can be used to
+ configure the MTU of non-internal ports.
