A few more details ...
....This bug exists in 'net' tree (and I believe previous releases) as 
well.
However my patch was generated on net-next, And there are other changes 
in the related area in net-next tree hence the patch will not apply on 
'net'.
Looks like its better for me to regenerate and submit against 'net'.  
will do.

Thanks,
Roopa
