This driver uses the same unregistered vendor id that the firewire core does (0xd00d1e). Perhaps this could be exposed as a define in firewire-constants.h? -2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci - - otherwise how will this driver know the max size of address window to - open for one packet write? 3. Maybe device_max_receive() and link_speed_to_max_payload() should be taken up by the firewire core? 4.
