ixgb(7d) Devices ixgb(7d)NAMEixgb - SUNWixgb, 10 Gigabit Ethernet driver for Intel 82597ex con‐
trollers and Sun Ethernet PCI-X Adapter (X5544A-4) adapters.
SYNOPSIS
/dev/ixgb
DESCRIPTION
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 Plat‐
forms. The Intel 10G controller incorporates both MAC and PHY func‐
tions 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 spec‐
ified by the IEEE 802.3ae specification.
CONFIGURATION
The following ixgb.conf configuration option is supported:
default_mtu
Upper limit on the maximum MTU size the driver allows. Intel
82597EX controller allows the configuration of jumbo frames. To
configure jumbo frame, use ifconfig(1M). Use ifconfig with the
adapter instance and the mtu argument (for example: ifconfig ixgb0
mtu 9000) to configure the adapter for the maximum allowable jumbo
frame size. Allowed range is 1500 - 9000.
APPLICATION PROGRAMMING INTERFACE
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:
o Maximum SDU is 9000 (ETHERMTU, as defined in <sys/ether‐
net.h>).
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
o SAP length value is −2 meaning the physical address compo‐
nent is followed immediately by a 2 byte SAP component
within the DLSAP address.
o Broadcast address value is Ethernet/IEEE broadcast address
(FF:FF:FF:FF:FF:FF).
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.
