Verifying KMP rpms compatibility with target kernel...
The kernel KMP rpms coming with MLNX_OFED_LINUX are not compatible with kernel: 3.10.0-1160.105.1.el7.x86_64
See log at /tmp/MLNX_OFED_LINUX.20398.logs/is_kmp_compat_check.log

The 3.10.0-1160.105.1.el7.x86_64 kernel is installed, MLNX_OFED_LINUX does not have drivers available for this kernel.
You can run mlnx_add_kernel_support.sh in order to to generate an MLNX_OFED_LINUX package with drivers for this kernel.
Or, you can provide '--add-kernel-support' flag to generate an MLNX_OFED_LINUX package and automatically start the installation.
