- OVS_BRIDGE: If TYPE is anything other than "OVSBridge", set to
the name of the OVS bridge to which the port should be attached.
- BOND_IFACES: For "OVSBond" interfaces, a list of physical
interfaces to bond together.
+ - OVS_TUNNEL_TYPE: For "OVSTunnel" interfaces, the type of the tunnel.
+ For example, "gre", "vxlan", etc.
+
+ - OVS_TUNNEL_OPTIONS: For "OVSTunnel" interfaces, this field should be
+ used to specify the tunnel options like remote_ip, key, etc.

Note
----
-"ifdown" on a bridge will not bring individual ports on the bridge
+* "ifdown" on a bridge will not bring individual ports on the bridge
down. "ifup" on a bridge will not add ports to the bridge. This
behavior should be compatible with standard bridges (with
TYPE=Bridge).
+* If 'ifup' on an interface is called multiple times, one can see
+"RTNETLINK answers: File exists" printed on the console. This comes from
+ifup-eth trying to add zeroconf route multiple times and is harmless.

Examples
--------
NETMASK=X.Y.Z.0
HOTPLUG=no
+Enable DHCP on the bridge:
+* Needs OVSBOOTPROTO instead of BOOTPROTO.
+* All the interfaces that can reach the DHCP server
+as a space separated list in OVSDHCPINTERFACES.
+
+DEVICE=ovsbridge0
+ONBOOT=yes
+DEVICETYPE=ovs
+TYPE=OVSBridge
+OVSBOOTPROTO="dhcp"
+OVSDHCPINTERFACES="eth0"
+HOTPLUG=no
+
+
+Adding Internal Port to ovsbridge0:
+
+==> ifcfg-intbr0 <==
+DEVICE=intbr0
+ONBOOT=yes
+DEVICETYPE=ovs
+TYPE=OVSIntPort
+OVS_BRIDGE=ovsbridge0
+HOTPLUG=no
+
+
+Internal Port with fixed IP address:
+
+DEVICE=intbr0
+ONBOOT=yes
+DEVICETYPE=ovs
+TYPE=OVSIntPort
+OVS_BRIDGE=ovsbridge0
+BOOTPROTO=static
+IPADDR=A.B.C.D
+NETMASK=X.Y.Z.0
+HOTPLUG=no
+
+Internal Port with DHCP:
+* Needs OVSBOOTPROTO or BOOTPROTO.
+* All the interfaces that can reach the DHCP server
+as a space separated list in OVSDHCPINTERFACES.
+

+DEVICETYPE=ovs
+TYPE=OVSIntPort

Adding physical eth0 to ovsbridge0 described above:

TYPE=OVSPort
-OVS_BRIDGE=internet
+OVS_BRIDGE=ovsbridge0
BOOTPROTO=none
HOTPLUG=no
ONBOOT=yes

+An Open vSwitch Tunnel:
+
+==> ifcfg-gre0 <==
