Abstract: A network interface device, an electronic device including same, and a method of operating same are provided. The network interface device is coupled to a host including a storage circuit. The network interface device includes a processing circuit and a packet receiving circuit which is used for receiving multiple network packets. The processing circuit performs the following steps: parsing the network packets to obtain multiple sequence numbers of the network packets; reordering the network packets based on the sequence numbers to generate reorder information; appending the reorder information to one of the network packets and generating packet order information, or generating the packet order information containing the reorder information; storing the packet order information in the storage circuit; and issuing an interrupt to the host. The packet receiving circuit or the processing circuit stores the network packets in the storage circuit before the processing circuit issues the interrupt.
