@Chander 

I know you are testing this. Maybe we can share information.

Could you run this patch and then share the results as well ?

--------------------------------------------------------------------
I am attaching the patch
base on 
git 	git://git.linaro.org/landing-teams/working/samsung/kernel.git
branch : enabled-3.3 or samsung-lt-v3.3-rc2
---------------------------------------------------------------
I tested the attached patch:
Without this patch, 
     1) ping works fine from x86 <-> Origen
     2) scp command not working:  ex.  scp dev@192.168.10.2:/home/dev/linaro/sample200MB

With patch (attached)
    1) ping works both ways
    2) scp dev@192.168.10.2:/home/dev/linaro/sample200MB
        11.1MB/s from x86 to Origen
