This is the most current release of the ixgbe driver for Linux, which 
supports kernel versions 2.6.18 up through 4.20.  It also has been tested on 
the following distributions:

	- RHEL 6.10
	- RHEL 7.6
	- SLES 12SP4
	- SLES 15
	- Ubuntu 18.04

Changes in this release:
	- Added support for 4.20 kernel version
	- Added support for SLES 12SP4 
	- Added support for RHEL 7.6

Note that while we attempt to keep the driver version number (5.5.3) 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.
