Electronic device and transmission control method

An electronic device comprising:

• a transmitting unit that transmits a packet to a component connected via a transmission path;
• a receiving unit that receives, from the component, identification information which identifies a packet that is to be received when packet transmission suspended due to the reinitialization is restarted;
• and
• a transmission control unit that controls, after the reinitialization has been completed and before the packet transmission is restarted by the transmitting unit, the transmitting unit such that the packet transmission is restarted in accordance with the identification information.

A transmission control method executed by an electronic device that includes a first component that receives a packet and a second component that transmits the packet, the transmission control method comprising:

• executing reinitialization of setting content related to a physical layer of a transmission path between the first component and the second component;
• transmitting, to the second component when the reinitialization is executed, identification information for identifying a packet that is to be received when packet transmission suspended due to the reinitialize is restarted;
• and
• notifying, after the reinitialization has been completed and before the first component restarts the packet transmission, the first component of an instruction to restart the packet transmission in accordance with the identification information.
