The command and responses are exchanged in form of packets. One or multiple packets are grouped under packet header. Each packet has packet type which describes the specific HFI and payload which holds the corresponding value for that HFI. Sys_init is the first packets sent to firmware, which initializes the firmware. Sys_image_version packet is to get the firmware version string.
