This is the most current release of the ixgbe driver for Linux, which supports kernel versions 2.6.18 up through 4.12. It also has been tested on the following distributions: - RHEL 6.9 - RHEL 7.3 - SLES 11SP4 - SLES 12PS2 Changes in this release: - Make use of build_skb in Rx code path for kernels >= 4.10 - Improved firmware version reporting - Added support for PF to set VF mac address to 0 - Resolved possible race condition in processing timestamp requests - Fixed error case to properly release resource bits - Improved compat kernel support - Various other bug fixes Note that while we attempt to keep the driver version number (5.2.1) 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 ixgbe driver is at least as up to date as the out of tree (OOT) driver found here.
