gld_mac_info(9S) Data Structures for Drivers gld_mac_info(9S)NAME
gld_mac_info - Generic LAN Driver MAC info data structure
Solaris architecture specific (Solaris DDI).
The Generic LAN Driver (GLD) Media Access Control (MAC) information (gld_mac_info) structure is the main data interface between the device-
specific driver and GLD. It contains data required by GLD and a pointer to an optional additional driver-specific information structure.
The gld_mac_info structure should be allocated using gld_mac_alloc() and deallocated using gld_mac_free(). Drivers can make no assumptions
about the length of this structure, which might be different in different releases of Solaris and/or GLD. Structure members private to GLD,
not documented here, should not be set or read by the device-specific driver.

Below is a description of the members of the gld_mac_info structure that are visible to the device driver.
gldm_private This structure member is private to the device-specific driver and is not used or modified by GLD. Conventionally,
this is used as a pointer to private data, pointing to a driver-defined and driver-allocated per-instance data
The following group of structure members must be set by the driver before calling gld_register(), and should not thereafter be modified by
the driver; gld_register() can use or cache the values of some of these structure members, so changes made by the driver after calling
gld_register() might cause unpredicted results.
gldm_reset Pointer to driver entry point; see gld(9E).
gldm_start Pointer to driver entry point; see gld(9E).
gldm_stop Pointer to driver entry point; see gld(9E).
gldm_set_mac_addr Pointer to driver entry point; see gld(9E).
gldm_set_multicast Pointer to driver entry point; see gld(9E).
gldm_set_promiscuous Pointer to driver entry point; see gld(9E).
gldm_send Pointer to driver entry point; see gld(9E).
gldm_intr Pointer to driver entry point; see gld(9E).
gldm_get_stats Pointer to driver entry point; see gld(9E).
gldm_ioctl Pointer to driver entry point; can be NULL; see gld(9E).
gldm_ident Pointer to a string containing a short description of the device. It is used to identify the device in system mes-
gldm_type The type of device the driver handles. The values currently supported by GLD are DL_ETHER (IEEE 802.3 and Ethernet
Bus), DL_TPR (IEEE 802.5 Token Passing Ring), and DL_FDDI (ISO 9314-2 Fibre Distributed Data Interface). This
structure member must be correctly set for GLD to function properly.
Note - Support for the DL_TPR and DL_FDDI media types is obsolete and may be removed in a future release of
gldm_minpkt Minimum Service Data Unit size -- the minimum packet size, not including the MAC header, that the device will
transmit. This can be zero if the device-specific driver can handle any required padding.
gldm_maxpkt Maximum Service Data Unit size -- the maximum size of packet, not including the MAC header, that can be transmitted
by the device. For Ethernet, this number is 1500.
gldm_addrlen The length in bytes of physical addresses handled by the device. For Ethernet, Token Ring, and FDDI, the value of
this structure member should be 6.
gldm_saplen The length in bytes of the Service Access Point (SAP) address used by the driver. For GLD-based drivers, this
should always be set to -2, to indicate that two-byte SAP values are supported and that the SAP appears after the
physical address in a DLSAP address. See the description under ``Message DL_INFO_ACK'' in the DLPI specification
for more details.
gldm_broadcast_addr Pointer to an array of bytes of length gldm_addrlen containing the broadcast address to be used for transmit. The
driver must allocate space to hold the broadcast address, fill it in with the appropriate value, and set
gldm_broadcast_addr to point at it. For Ethernet, Token Ring, and FDDI, the broadcast address is normally 0xFF-FF-
gldm_vendor_addr Pointer to an array of bytes of length gldm_addrlen containing the vendor-provided network physical address of the
device. The driver must allocate space to hold the address, fill it in with information read from the device, and
set gldm_vendor_addr to point at it.
gldm_ppa The Physical Point of Attachment (PPA) number for this instance of the device. Normally this should be set to the
instance number, returned from ddi_get_instance(9F).
gldm_devinfo Pointer to the dev_info node for this device.
gldm_cookie The interrupt block cookie returned by ddi_get_iblock_cookie(9F), ddi_add_intr(9F), ddi_get_soft_iblock_cookie(9F),
or ddi_add_softintr(9F). This must correspond to the device's receive interrupt, from which gld_recv() is called.
gldm_capabilities Bit-field of device capabilities. If the device is capable of reporting media link state, the GLD_CAP_LINKSTATE bit
should be set.
