.SH NAME
i40e \-This file describes the Linux* Base Driver
for the Intel Ethernet Controller XL710 Family of Controllers.
.SH SYNOPSIS
.PD 0.4v
modprobe i40e [<option>=<VAL1>,<VAL2>,...]
.PD 1v
.SH DESCRIPTION
This driver is intended for \fB2.6.32\fR and newer kernels. A version of the driver may already be included by your distribution and/or the kernel.org kernel.
This driver includes support for any 64 bit Linux supported system, including Itanium(R)2, x86_64, PPC64, ARM, etc.
.LP
This driver is only supported as a loadable module at this time. Intel is not supplying patches against the kernel source to allow for static linking of the drivers.
For questions related to hardware requirements, refer to the documentation
supplied with your Intel adapter. All hardware requirements listed apply to
use with Linux.
.SH Jumbo Frames
.LP
Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU) to a value larger than the default value of 1500.
Use the ifconfig command to increase the MTU size. For example, enter the following where <x> is the interface number:
ifconfig eth<x> mtu 9000 up
Alternatively, you can use the ip command as follows:
ip link set mtu 9000 dev eth<x>
ip link set up dev eth<x>
.LP
NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides with the maximum Jumbo Frames size of 9728 bytes.
NOTE: This driver will attempt to use multiple page sized buffers to receive each jumbo packet. This should help to avoid buffer starvation issues when allocating receive packets.
See the section "Jumbo Frames" in the Readme.
.SH SUPPORT

For additional information regarding building and installation, see the
README
included with the driver.

If an issue is identified with the released source code on a supported kernel with a supported adapter, email the specific information related to the issue to [email protected].
