Flow programmer service is not relaying all the details of flow removal event to the listeners

Openflow specs 1.0 says that 1.0 compliant switch should send the following details to the controller with flow removal event

/* Flow removed (datapath -> controller). */
struct ofp_flow_removed {
struct ofp_header header;
struct ofp_match match; /* Description of fields. */
uint64_t cookie; /* Opaque controller-issued identifier. */
uint16_t priority; /* Priority level of flow entry. */
uint8_t reason; /* One of OFPRR_*. */
uint8_t pad[1]; /* Align to 32-bits. */
uint32_t duration_sec; /* Time flow was alive in seconds. */
uint32_t duration_nsec; /* Time flow was alive in nanoseconds beyond
duration_sec. */
uint16_t idle_timeout; /* Idle timeout from original flow mod. */
uint8_t pad2[2]; /* Align to 64-bits. */
uint64_t packet_count;
uint64_t byte_count;
};

Current implementation of flowprogrammer is not relaying following info from the above structure to its flow removal event listener.

uint8_t reason; /* One of OFPRR_*. */
uint32_t duration_sec; /* Time flow was alive in seconds. */
uint32_t duration_nsec; /* Time flow was alive in nanoseconds beyond
duration_sec. */
uint64_t packet_count;
uint64_t byte_count;

Alessandro mentioned that FlowOnNode class is better choice for relaying all the above mentioned details to the listener. But FlowOnNode does not relay [uint8_t reason ] parameter, so it requires some thought.
