openSUSE Leap 15.1 on Fujitsu PRIMERGY RX2540 M4/M5

I heard a customer who would like to use openSUSE Leap on PRIMERGY RX2540 M4/M5. Although it's not officially supported, since SUSE Linux Enterprise Server (SLE or SLES) 15 is supported, openSUSE Leap should work.

I quickly tested openSUSE Leap 15.1 on RX2540 M4 with ServerView Suite (ServerView Agent for Linux and ServerView RAID Manager), and everything seems to work ok.
One thing to check is the onboard X722 network port driver (i40e). Fujitsu provides the OEM driver (i40e 2.10.19.30) for SLES 15 SP1 and this is required to use the latest firmware for X722, but this driver cannot be used for openSUSE Leap 15.1 as the driver is not built for the openSUSE kernel. That means you need to build the i40e driver 2.10.19.30 from the source code. You can obtain the source code from the Intel download site, or from Sourceforge (https://sourceforge.net/projects/e1000/files/i40e%20stable/2.10.19.30/).

When compiling the i40e driver, you probably see the following errors:
