features:
- The DSCP value for outer headers in openvswitch overlay tunnel ports can
now be set through a configuration option ``dscp`` for both OVS and
linuxbridge agents.
- DSCP can also be inherited from the inner header through a new
boolean configuration option ``dscp_inherit`` for both openvswitch and
linuxbridge. If this option is set to true, then the value of ``dscp``
will be ignored.
deprecations:
- the ``tos`` configuration option in vxlan group for linuxbridge is
deprecated and replaced with the more precise option ``dscp``. The
TOS value is made of DSCP and ECN bits. It is not possible to set the
ECN value through the TOS value, and ECN is always inherited from the
inner in case of tunneling.
