Pravin, does the GRE note look correct?

- Add 'mtu_request' column to the Interface table. It can be used to
configure the MTU of the ports.
+Known issues:
+ - Using openvswitch module in conjunction with upstream Linux tunnels:
+ * When using the openvswitch module distributed with OVS against kernel
+ versions 4.4-4.6, the openvswitch module cannot be loaded or used at the
+ same time as "ip_gre".
+ - Conntrack FTP ALGs: When using the openvswitch module distributed with
+ OVS, particular Linux distribution kernels versions may provide diminished
+ functionality. This typically affects active FTP data connections when
+ using "actions=ct(alg=ftp),..." in flow tables. Specifically:
+ * Centos 7.1 kernels (3.10.0-2xx) kernels are unable to correctly set
+ up expectations for FTP data connections in multiple zones,
+ eg "actions=ct(zone=1,alg=ftp),ct(zone=2,alg=ftp),...". Executing the
+ "ct" action for subsequent data connections may fail to determine that
+ the data connection is "related" to an existing connection.
+ * Centos 7.2 kernels (3.10.0-3xx) kernels may not establish FTP ALG state
+ correctly for NATed connections. As a result, flows that perform NAT,
+ eg "actions=ct(nat,ftp=alg,table=1),..." may fail to NAT the packet,
+ and will populate the "ct_state=inv" bit in the flow.
