.Nd "Intel(R) 10Gb Ethernet driver"
|
||
|
|
.Sh SYNOPSIS
|
||
|
|
.Cd "ixg* at pci? dev ? function ?"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver provides support for PCI 10Gb Ethernet adapters based on
|
||
|
|
the Intel(R) 82598EB and 82599 10 GbE Controllers.
|
||
|
|
The driver supports Jumbo Frames, TCP Segmentation Offload (TSO).
|
||
|
|
.Pp
|
||
|
|
For questions related to hardware requirements,
|
||
|
|
refer to the documentation supplied with your Intel 10GbE adapter.
|
||
|
|
All hardware requirements listed apply to use with
|
||
|
|
.Nx .
|
||
|
|
.Pp
|
||
|
|
Support for Jumbo Frames is provided via the interface MTU setting.
|
||
|
|
Selecting an MTU larger than 1500 bytes with the
|
||
|
|
.Xr ifconfig 8
|
||
|
|
utility configures the adapter to receive and transmit Jumbo Frames.
|
||
|
|
On .Nx ,
|
||
|
|
the maximum MTU size for Jumbo Frames is 9000 bytes.
|
||
|
|
.Pp
|
||
|
|
This driver version supports VLANs.
|
||
|
|
For information on enabling VLANs, see
|
||
|
|
.Xr ifconfig 8 .
|
||
|

.Sh HISTORY
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
device driver comes from
|
||
|
|
.Fx ,
|
||
|
|
where it is called
|
||
|
|
.Xr ixgbe 4 .
|
||
|
|
It first appeared in
|
||
|
|
.Nx 6.0 .
|
||
|
|
.Sh AUTHORS
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver was written by
|
||
|
|
.An Intel Corporation Aq freebsdnic@mailbox.intel.com .
|
||
|
|
It was imported from
|
||
|
|
.Fx
|
||
|
|
into
|
||
|
|
.Nx
|
||
|
|
by
|
||
|
|
.An David Young Aq dyoung@NetBSD.org .
|
||
|
|
.Sh BUGS
|
||
|
|
The hardware supports a maximum MTU of 16114 bytes, but the
|
||
|
|
.Nx
|
||
|
|
port of the driver supports only 9000 bytes.
|
||
|
|
.Pp
|
||
|
|
The hardware supports Message-Signalled Interrupts (MSI and MSI-X)
|
||
|
|
and Receive-Side Scaling (RSS), however, these features are not
|
||
|
|
enabled in the
|
||
|
|
.Nx
|
||
|
|
driver at this time.
