func (br *OVSBridge) CreatePort(name, ifDev string, externalIDs map[string]interface{}) (string, Error)

CreatePort creates a port with the specified name on the bridge, and connects the interface specified by ifDev to the port. If externalIDs is not empty, the map key/value pairs will be set to the port's external_ids.

func (*OVSBridge) CreateTunnelPort 

func (br *OVSBridge) CreateTunnelPort(name string, tunnelType TunnelType, ofPortRequest int32) (string, Error)

If remoteIP is not empty, it will be set to the tunnel port interface options; otherwise flow based tunneling will be configured. psk is for the pre-shared key of IPsec ESP tunnel. If it is not empty, it will be set to the tunnel port interface options. Flow based IPsec tunnel is not supported, so remoteIP must be provided too when psk is not empty. If externalIDs is not nil, the IDs in it will be added to the port's external_ids.

If the "wait" operation times out or the interface is not found, or the ofport is invalid, value 0 and an error will be returned.
