 * General ibnex IOCTLs
 *
 * IBNEX_CTL_GET_API_VER
 * ======================
 *
 * Gets the version number of the API that IB nexus currently supports.
 *
 * arg - pointer to a structure of type ibnex_ctl_api_ver_t
 *
 * Caller does not set any field of this structure. When this IOCTL is issued,
 * ib nexus will set api_ver_num field to the currently supported API
 * version number.
 *
 * The caller could issue this IOCTL prior to issuing any other general
 * ibnex IOCTLs to detect incompatible changes to the API. The caller may
 * call other IOCTLs only if the api_ver_num matches the API version number
 * used by the caller.
 *
 *
 * IBNEX_CTL_GET_HCA_LIST
 * ======================
 *
 * Gets GUIDs of all HCAs in the system
 *
 * arg - pointer to a structure of type ibnex_ctl_get_hca_list_t
 *
 * Caller allocates memory for HCA GUIDs. Sets hca_guids field to point to the
 * allocated memory. Sets hca_guids_alloc_sz to the number of GUIDs for which
 * memory has been allocated.
 *
 * Upon successful return from the IOCTL, nhcas will contain the number of
 * HCAs in the system. HCA GUIDs will be copied into hca_guids array.
 * The number of GUIDs copied are nhcas or hca_guids_alloc_sz which ever is
 * smaller.
 *
 *
 * IBNEX_CTL_QUERY_HCA
 * ===================
 *
 * Query HCA attributes
 *
 * arg - pointer to a structure of type ibnex_ctl_query_hca_t
 *
 * Caller sets hca_guid field of this structure.
 *
 * Caller allocates memory for hca device path. Sets hca_device_path to point
 * to the allocated memory and hca_device_path_alloc_sz to the number of bytes
 * allocated.
 *
 * Upon successful return from the IOCTL, hca_info will contain HCA attributes
 * for the specified GUID. hca_info.hca_device_path_len will contain the actual
 * string length of the hca device path plus one (for the terminating null
 * character). hca_info.hca_device_path will point to null terminated hca device
 * path string if the caller allocated memory for the hca device path is large
 * enough to hold the hca device path and the terminating null character.
 * Otherwise hca_info.hca_device_path will be set to NULL.
 *
 *
 * IBNEX_CTL_QUERY_HCA_PORT
 * ========================
 *
 * Query HCA port attributes
 *
 * arg - pointer to a structure of type ibnex_ctl_query_hca_port_t
 *
 * Caller sets hca_guid and port_num fields.
 *
 * Caller allocates memory for sgid entries. Sets sgid_tbl to point to
 * the allocated memory and sgid_tbl_alloc_sz to the number of sgid entries
 * for which memory has been allocated.
 *
 * Caller allocates memory for pkey entries. Sets pkey_tbl to point to
 * the allocated memory and pkey_tbl_alloc_sz to the number of pkey entries
 * for which memory has been allocated.
 *
 * Upon successful return from the IOCTL, port_info will contain HCA port
 * attributes for the specified HCA port. port_info.p_sgid_tbl_sz will contain
 * the actual number of sgids associated with this port. port_info.p_pkey_tbl_sz
 * will contain the actual number of pkeys associated with this port.
 *
 * port_info.p_sgid_tbl will point to an array containing sgids. The number of
 * sgids in the array is sgid_tbl_alloc_sz or port_info.p_sgid_tbl_sz
 * whichever is smaller.
 *
 * port_info.p_pkey_tbl will point to an array containing pkeys. The number of
 * pkeys in the array is pkey_tbl_alloc_sz or port_info.p_pkey_tbl_sz
 * whichever is smaller.
 *
 * Error numbers for the above ioctls upon failure:
 *   EINVAL	Invalid parameter passed
 *   EFAULT	A fault occurred copying data to or from the user space
 *		to the kernel space.
 *   ENXIO	Specified HCA GUID does not exist
 *   ENOENT	Specified HCA port does not exist
 *
