摘要： Methods, systems and computer program products are described for transferring aggregated data packets over an I/O interface from a host to a multiport embedded device. For example, a method includes receiving, by the device from the host, a single write command that (i) specifies two or more ports from among multiple ports of the device, and (ii) includes two or more data packets to be respectively written to the specified ports. The multiple ports of the device are mapped to corresponding locations of memory of the device. The method further includes saving, by the device in response to the single write command, the two or more data packets at two or more memory locations to which the specified ports are mapped. Additionally, the method includes sending, upon saving the data packets, a single notification to the host indicating that the device is ready to receive another write command.
