+ * Create a custom hash key on basis of offset of start of packet and size.
+ * for e.g. if we need GRE packets (non-vlan and without any extra headers)
+ * to be hashed on basis of inner IP header, we will provide offset as:
+ * 14 (eth) + 20 (IP) + 4 (GRE) + 12 (Inner Src offset) = 50 and size
+ * as 8 bytes.
+ *
+ * @param port_id
+ *    The port identifier of the Ethernet device.
+ * @param offset
+ *    Offset from the start of packet which needs to be included to
+ *    calculate hash
+ * @param size
+ *    Size of the hash input key
+ *
+ * @return
+ *   - 0 if successful.
+ *   - Negative in case of failure.
