Changelog for ixgbe-5.19.9

Fix compilation under RHEL 9.3 & 8.9

This is the most current release of the ixgbe driver for Linux, which
supports kernel versions 2.6.18 up through 6.4. It also has been tested on
the following distributions:

- RHEL 8.8
- RHEL 9.2
- SLES 12sp5
- SLES 15sp5
- Ubuntu 22.04

Changes in this release:
- Added support for 6.4 kernel version
- RHEL 8.8
- RHEL 9.2
- SLES 15sp5

Note that while we attempt to keep the driver version number (5.19.6) in sync
with its counterpart in the Linux kernel that has similar functionality this
is far from authoritative. If you are using a newer kernel.org kernel or
distro it is likely that its ixgbe driver is at least as up to date as the
out of tree (OOT) driver found here.

Overview

This driver supports kernel versions 2.6.x and newer. However, some features
may require a newer kernel version. The associated Virtual Function (VF) driver
for this driver is ixgbevf.

Driver information can be obtained using ethtool, lspci, and ip. Instructions
on updating ethtool can be found in the section Additional Configurations later
in this document.

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.

This driver supports XDP (Express Data Path) on kernel 4.14 and later and
AF_XDP zero-copy on kernel 4.18 and later. Note that XDP is blocked for frame
sizes larger than 3KB.

NOTE: Devices based on the Intel(R) Ethernet Connection X552 and Intel(R)
Ethernet Connection X553 do not support the following features:

• Energy Efficient Ethernet (EEE)
• Intel PROSet for Windows Device Manager
• Intel ANS teams or VLANs (LBFO is supported)
• Fibre Channel over Ethernet (FCoE)
• Data Center Bridging (DCB)
• IPSec Offloading
• MACSec Offloading
  In addition, SFP+ devices based on the Intel(R) Ethernet Connection X552 and
  Intel(R) Ethernet Connection X553 do not support the following features:
• Speed and duplex auto-negotiation.
• Wake on LAN
• 1000BASE-T SFP Modules

Identifying Your Adapter

The driver is compatible with devices based on the following:

• Intel(R) Ethernet Controller 82598
• Intel(R) Ethernet Controller 82599
• Intel(R) Ethernet Controller X520
• Intel(R) Ethernet Controller X540
• Intel(R) Ethernet Controller x550
• Intel(R) Ethernet Controller X552
• Intel(R) Ethernet Controller X553

82599-BASED ADAPTERS

NOTES:

• If your 82599-based Intel(R) Network Adapter came with Intel optics or is an
  Intel(R) Ethernet Server Adapter X520-2, then it only supports Intel optics
  and/or the direct attach cables listed below.
• When 82599-based SFP+ devices are connected back to back, they should be
  set to the same Speed setting via ethtool. Results may vary if you mix
  speed settings.

laser off and on.

82599-based QSFP+ Adapters

NOTES:

• If your 82599-based Intel(R) Network Adapter came with Intel optics, it
  only supports Intel optics.
• 82599-based QSFP+ adapters only support 4x10 Gbps connections.
  1x40 Gbps connections are not supported. QSFP+ link partners must be
  configured for 4x10 Gbps.
• 82599-based QSFP+ adapters do not support automatic link speed detection.
  The link speed must be configured to either 10 Gbps or 1 Gbps to match the
  link partners speed capabilities. Incorrect speed configurations will result
  in failure to link.
• Intel(R) Ethernet Converged Network Adapter X520-Q1 only supports the
  optics and direct attach cables listed below.

82598-BASED ADAPTERS

NOTES:

• Intel(r) Ethernet Network Adapters that support removable optical modules
  only support their original module type (for example, the Intel(R) 10 Gigabit
  SR Dual Port Express Module only supports SR optical modules). If you plug
  in a different type of module, the driver will not load.

• Hot Swapping/hot plugging optical modules is not supported.

• Only single speed, 10 gigabit modules are supported.

• LAN on Motherboard (LOMs) may support DA, SR, or LR modules. Other module
  types are not supported. Please see your system documentation for details.

Important Notes

Do not unload port driver if VF with active VM is bound to it

Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
Once the VM shuts down, or otherwise releases the VF, the command will complete.

Configuring SR-IOV for improved network security

In a virtualized environment, on Intel(R) Ethernet Network Adapters that
support SR-IOV, the virtual function (VF) may be subject to malicious behavior.
Software-generated layer two frames, like IEEE 802.3x (link flow control), IEEE
802.1Qbb (priority based flow-control), and others of this type, are not
expected and can throttle traffic between the host and the virtual switch,
reducing performance. To resolve this issue, and to ensure isolation from
unintended traffic streams, configure all SR-IOV enabled ports for VLAN tagging
from the administrative interface on the PF. This configuration allows
unexpected, and potentially malicious, frames to be dropped.

Building and Installation

To manually build the driver

1. Move the base driver tar file to the directory of your choice.
   For example, use '/home/username/ixgbe' or '/usr/local/src/ixgbe'.

2. Untar/unzip the archive, where <x.x.x> is the version number for the
   driver tar f...
