NAME
ixgbe - Intel 10Gb PCI Express NIC Driver
DESCRIPTION
The
ixgbe 10 Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface,
dlpi(7P), on Intel 10-Gigabit PCI Express Ethernet controllers.
The ixgbe driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, and error recovery and reporting.
The ixgbe driver supports the following Intel 10-Gigabit PCI Express Ethernet controllers:
-
o
-
Intel Ethernet Controller 82598EB Family
-
o
-
Intel Ethernet Controller 82599EB (X520) Family
-
o
-
Intel Ethernet Controller X540 Family
-
o
-
Intel Ethernet Controller X550 Family
The ixgbe driver and hardware support auto-negotiation, a protocol specified by the IEEE 802.3ae specification.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device,
/dev/ixgbe, is used to access all Intel 10-Gigabit PCI Express Ethernet devices installed within the system.
The ixgbe driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of ixgbe instances and for ixgbe 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 your DL_INFO_REQ are:
-
o
-
DLSAP address length is 8.
-
o
-
SAP (Service Access Point) length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP component within the DLSAP address.
-
o
-
Broadcast address value is the 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 SAP with the stream.
CONFIGURATION
By default, the ixgbe driver performs auto-negotiation to select the link speed and mode. Link speed and mode can only be 10000 Mbps full-duplex for fiber, and only 10000, 1000, or 100 Mbps full-duplex for copper. See the IEEE802.3 standard for more information.
