@Rama Wow you are reviving an long dead thread here.
I would strongly suggest that you start a new thread since info shared in this thread is probably not valid anymore.
BUT, some things to consider. What version of FOG are you using? If you are using FOG 1.2.0 stable then the newest kernel you may safely used is 4.1.2 (which should contain the driver you seek). Kernels 4.4.x and greater can only be used on the trunk build of fog 1.2.0 or fog 1.3.0-rc series.
If you run a compatibility test, does it report both nic and hard drive passing the test?
