The ixgb 10 Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface, DLPI on Intel 82597ex 10 Gigabit Ethernet controllers and Sun 10 Gigabit Ethernet PCI-X Adapter (X5544A-4) on x86 Platforms. The Intel 10G controller incorporates both MAC and PHY functions and provides 10G (fiber) Ethernet operation on the SR and LR connectors. The Sun 10 Gigabit Ethernet PCI-X Adapter (X5544A-4) is a 133 MHz PCI-X 10 Gigabit Ethernet card utilizing the Intel 82597EX PCI-X MAC controller with XFP-based 10GigE optics.
The ixgb driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support and error recovery and reporting.
The ixgb driver and hardware support auto-negotiation, a protocol specified by the IEEE 802.3ae specification.
The following ixgb.conf configuration option is supported:
The cloning character-special device /dev/ixgb is used to access all Intel 10G controllers and Sun 10 Gigabit Ethernet PCI-X adapters (X5544A-4) installed within the system
The ixgb driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of ixgb instances and for ixgb instances to be aggregated. See dladm(1M) for more details.
You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de-initialized (stopped) at last detach.
The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ are:
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.
By default, the ixgb driver performs auto-negotiation to select the 10G link speed.
