features:
- Enable creation of VXLANs with different multicast addresses
in linuxbridge agent allocated by VNI-address mappings.
A new config option ``multicast_ranges`` was introduced.
other:
- Example configuration of ``multicast_ranges`` in
ml2_conf.ini under the ``[vxlan]`` config. section
``multicast_ranges = 224.0.0.10:10:90,225.0.0.15:100:900``.
For VNI between 10 and 90, the multicast address
224.0.0.0.10 will be used, and for 100 through 900
225.0.0.15 will be used. Other VNI values will get
standard ``vxlan_group`` address. For more info see RFE
