IXGBE(7D)IXGBE(7D)NAMEixgbe - Intel 10Gb PCI Express NIC Driver
SYNOPSIS
/dev/ixgbe*
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 con‐
trollers.
The ixgbe driver functions include controller initialization, frame
transmit and receive, promiscuous and multicast support, and error
recovery and reporting.
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 num‐
ber 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 Maximum SDU is 16366.
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
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.
