-Post-v1.2.0
+port-v1.4.0
------------------------
+
+
+v1.4.0 - xx xxx xxxx
+------------------------
+ - New "VLAN splinters" feature to work around buggy device drivers
+ in old Linux versions. (This feature is deprecated. When
+ broken device drivers are no longer in widespread use, we will
+ delete this feature.) See ovs-vswitchd.conf.db(5) for more
+ information.
+ - OpenFlow:
+ - Added ability to match on IPv6 flow label through NXM.
+ - Added ability to match on ECN bits in IPv4 and IPv6 through NXM.
+ - Added ability to match on TTL in IPv4 and IPv6 through NXM.
+ - Added ability to modify ECN bits in IPv4.
+ - Added ability to modify TTL in IPv4.
+ - ovs-vswitchd:
+ - Don't require the "normal" action to use mirrors. Traffic will
+ now be properly mirrored for any flows, regardless of their
+ actions.
+ - Track packet and byte statistics sent on mirrors.
+ - The sFlow implementation can now usually infer the correct agent
+ device instead of having to be told explicitly.
- ovs-appctl:
- - New "version" command to determine version of running daemon
+ - New "fdb/flush" command to flush bridge's MAC learning table.
+ - ovs-test:
+ - A new distributed testing tool that allows one to diagnose performance
+ and connectivity issues. This tool currently is not included in RH or
+ Xen packages.
+ - RHEL packaging now supports integration with Red Hat network scripts.
+
+
+v1.3.0 - xx xxx xxxx
+------------------------
+ - OpenFlow:
+ - Added an OpenFlow extension which allows the "output" action to accept
+ NXM fields.
+ - Added an OpenFlow extension for flexible learning.
+ - Bumped number of NXM registers from four to five.
+ - ovs-appctl:
+ - New "version" command to determine version of running daemon.
+ - If no argument is provided for "cfm/show", displays detailed
+ information about all interfaces with CFM enabled.
+ - If no argument is provided for "lacp/show", displays detailed
+ information about all ports with LACP enabled.
+ - ovs-dpctl:
+ - New "set-if" command to modify a datapath port's configuration.
- ovs-vswitchd:
- The software switch now supports 255 OpenFlow tables, instead
of just one. By default, only table 0 is consulted, but the
new NXAST_RESUBMIT_TABLE action can look up in additional
tables. Tables 128 and above are reserved for use by the
switch itself; please use only tables 0 through 127.
+ - Add support for 802.1D spanning tree (STP).
+ - Fragment handling extensions:
+ - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4
+ fields are made available for matching in fragments with
+ offset 0.
+ - New NXM_NX_IP_FRAG match field for matching IP fragments (usable
+ via "ip_frag" in ovs-ofctl).
+ - New ovs-ofctl "get-frags" and "set-frags" commands to get and set
+ fragment handling policy.
+ - CAPWAP tunneling now supports an extension to transport a 64-key. By
+ default it remains compatible with the old version and other
+ standards-based implementations.
+ - Flow setups are now processed in a round-robin manner across ports
+ to prevent any single client from monopolizing the CPU and conducting
+ a denial of service attack.
+ - Added support for native VLAN tagging. A new "vlan_mode"
+ parameter can be set for "port". Possible values: "access",
+ "trunk", "native-tagged" and "native-untagged".
+ - test-openflowd has been removed. Please use ovs-vswitchd instead.
