-Post-v2.7.0
----------------------
- - ovs-ofctl can now accept and display port names in place of numbers. By
- default it always accepts names and in interactive use it displays them;
- use --names or --no-names to override. See ovs-ofctl(8) for details.

+ "table#". These are not helpful names for the purpose of accepting
+ and displaying table names, so now tables by default have no names.
+ * The "null" interface type, deprecated since 2013, has been removed.
+ * Add minimum network namespace support for Linux.
+ * New command "lacp/show-stats"
+ - ovs-ofctl:
+ * ovs-ofctl now accepts and display table names in place of numbers. By

+ use --names or --no-names to override. See ovs-ofctl(8) for details.
+ - ovs-vsctl: New commands "add-bond-iface" and "del-bond-iface".
+ - OpenFlow:
+ * OFPT_ROLE_STATUS is now available in OpenFlow 1.3.

+ and reply with a RST for TCP or ICMPv4/ICMPv6 unreachable message for
+ other IPv4/IPv6-based protocols whenever a reject ACL rule is hit.
+ * ACL match conditions can now match on Port_Groups as well as address
+ sets that are automatically generated by Port_Groups.

+ * Add support for vHost dequeue zero copy (experimental)
+ - Userspace datapath:
+ * Output packet batching support.
