I was finally able to root-cause issue, and have prepared a proper fix.
Turns out, the len calculation was not done properly. So, this revert patch is 
now no longer required.

If this revert patch is not yet merged in net-next, and if its OK with you then,
could you please drop this revert patch from your patch-queue ?
I will get the proper fix submitted for this regression.

Sorry for the trouble caused by this LSO related patch.

Thanks,
Kumar.
