Detailed Description

struct fw_cdev_send_request - Send an asynchronous request packet : Transaction code of the request : Length of outgoing payload, in bytes : 48-bit offset at destination node : Passed back to userspace in the response event : Userspace pointer to payload : The bus generation where packet is valid

Send a request to the device. This ioctl implements all outgoing requests. Both quadlet and block request specify the payload as a pointer to the data in the field. Once the transaction completes, the kernel writes an &fw_cdev_event_response event back. The field is passed back to user space in the response event.
