I did not run the installer properly, I used this installed command:
./mlnxofedinstall --force --without-dkms --with-nvmf
When it should be:
./mlnxofedinstall --force --without-dkms --with-nvmf --add-kernel-support
Complete installation steps that worked for me:
tar xvzf MLNX_OFED_LINUX-4.4-1.0.0.0-ubuntu18.04-x86_64.tgz
cd MLNX_OFED_LINUX-4.4-1.0.0.0-ubuntu18.04-x86_64/
./mlnxofedinstall --force --without-dkms --with-nvmf --add-kernel-support
/etc/init.d/openibd restart
