Rev 1.7
The DKMS (on Debian based OS) and the weak-modules (RedHat OS) mechanisms rebuild
the initrd/initramfs for the respective kernel in order to add the MLNX_OFED drivers.
When installing MLNX_OFED without DKMS support on Debian based OS, or without
KMP support on RedHat or any other distribution, the initramfs will not be changed. There-
fore, the inbox drivers may be loaded on boot. In this case, openibd service script will auto-
matically unload them and load the new drivers that come with MLNX_OFED.
# mount -o ro,loop MLNX_OFED_LINUX-<ver>-<OS label>-<CPU arch>.iso /mnt

Note that all other Mellanox, OEM, OFED, RDMA or Distribution IB packages will be removed.
