I am trying to install MLNX_OFED 4.5-1.0.1.0 on a Fedora 28 machine. The kernel version is 4.20.17-100.fc28.x86_64. Running the mlnxofedinstall gives the following error message and:
The 4.20.17-100.fc28.x86_64 kernel is installed, MLNX_OFED_LINUX does not have drivers available for this kernel.
Running the mlnx_add_kernel_support.sh using the below command
./mlnx_add_kernel_support.sh -m /path/to/MLNX_OFED_LINUX-4.5-1.0.1.0-fc28-x86_64/ --kernel 4.20.17-100.fc28.x86_64 --make-tgz
also fails with error messages
Failed to build mlnx-ofa_kernel 4.5 RPM
and looking at the rpm build log for errors gives these logs

What can be done to fix these errors? Also what is the officially supported kernel version by MLNX_OFED 4.5.1.0.1.0 ?
