This is the most current release of the ixgbevf driver for Linux, which supports kernel versions 2.6.18 up through 5.16. It also has been tested on the following distributions: - RHEL 7.9 - RHEL 8.5 - RHEL 8.6 - SLES 12sp5 - SLES 15sp3 - SLES 15sp4 - Ubuntu 19.04 - Ubuntu 20.04 Changes in this release: - Added support for RHEL 8.6 - Added support for SLES 15sp4 Note that while we attempt to keep the driver version number (4.15.1) 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 ixgbevf driver is at least as up to date as the out of tree (OOT) driver found here.
