Sometimes it's useful to know the FireWire speed of the request that has just come in to a fw_address_handler callback. As struct fw_request is opaque we can't peek inside to get the speed out of the struct fw_packet that's just inside. For example, the SBP-2 spec says: "The speed at which the block write request to the MANAGEMENT_AGENT register is received shall determine the speed used by the target for all subsequent requests to read the initiator’s configuration ROM, fetch ORB’s from initiator memory or store status at the initiator’s status_FIFO. Command block ORB’s separately specify the speed for requests addressed to the data buffer or page table."
