It will create a char device once loaded, offering interfaces (open, close, read, write and poll) to BMA to send/receive RESTful messages between BMC software. When the message is longer than 1KB, it will be cut into packets of 1KB. The other side, BMC's cdev_veth driver, will assemble these packets back into original mesages.

Again, you never replied to my questions. In general, a char dev
interface to 'firmware' is not allowed. So i suggest you drop this
patch.
