1. How to Install RHEL6.x using ConnectX-4/Lx Ethernet Drivers
===============================================================================
1. Create Driver Update Disk for RHEL6.x.
   $ gzip -d dd-rhel6.x-mlnx-en-3.1-1.0.0-x86_64.iso.gz
   $ mkdir /tmp/initrd_update
   $ cp dd-rhel6.x-mlnx-en-3.1-1.0.0-x86_64.iso /tmp/initrd_update/dd.img
   $ cd /tmp/initrd_update
   $ find . | cpio --quiet -o -H newc | gzip -9 > /tmp/initrd_update.img
   $ cp /tmp/initrd_update.img /tftpboot/images/rhel/x86_64/6.x/dd.img
2. Update PXE Configuration.
   Example:
   label Rhel 6.x-x86_64-DD
     menu label rhel6x-x86_64-dd
     kernel images/rhel/x86_64/66/vmlinuz
     IPAPPEND 2
     append initrd=images/rhel/x86_64/6.x/initrd.img,images/rhel/x86_64/6.x/dd.img repo=http://10.0.0.1/RH/6.X/x86_64/ ks=http://10.0.0.1/confs/images/rhel/x86_64/6.x/ks_dd.cfg ksdevice=bootif
3. Add to the kickstart file the post install section below.
   %post --interpreter /bin/bash
   #install and autostart Mellanox kernel module
   yum localinstall -y /root/DD-0/*mlnx*.rpm
