ixgbe-5.18.11

This is the most current release of the ixgbe driver for Linux, which
supports kernel versions 2.6.18 up through 6.1. It also has been tested on
the following distributions:

- RHEL 8.7
- RHEL 9.1
- SLES 12sp5
- SLES 15sp4
- Ubuntu 22.04

Changes in this release:
- Added support for 6.1 kernel version
- Various bug fixes

Note that while we attempt to keep the driver version number (5.18.11) 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.
