* when sending messages to the bmc driver, the data portion is now variable
* (the caller must allocate enough space to store the all structure members,
* plus enough space to cover the amount of data in the request), e.g.:
*
* bmc_msg_t *msg = malloc(offsetof(bmc_msg_t, msg) + sizeof(bmc_req_t) + 10);
*
* The amount allocated for the message is (# of bytes before the msg field) +
* the size of a bmc_req_t (which includes SEND_MAX_PAYLOAD_SIZE
* bytes in the data field), plus an additional 10 bytes for the data
* field (so the data field would occupy (SEND_MAX_PAYLOAD_SIZE + 10)
* bytes). The datalength member must reflect the amount of data in the
* request's data field (as was required when using the ioctl interface).
