ixgbevf(7D) Devices ixgbevf(7D)NAMEixgbevf - Intel 10Gb PCI Express NIC Virtual Function Driver
SYNOPSIS
/dev/ixgbevf*
DESCRIPTION
The ixgbevf 10 Gb NIC Virtual Function 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 82599 NIC and later NICs.
The ixgbevf driver functions include controller initialization, frame
transmit and receive, promiscuous and multicast support, and error
recovery and reporting.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/ixgbevf, is used to access
the virtual functions of the 82599 NIC and other later Intel 10Gb NIC
devices installed within the system.
The ixgbevf driver is managed by the dladm(1M) command line utility,
which allows VLANs to be defined on top of ixgbevf instances and for
ixgbevf instances to be aggregated. See dladm(1M) for 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 1500.
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).
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, Link speed and mode can only be 10000 Mbps full-duplex. See
the IEEE 802.3ae Specificiation for more information.
