The lro manager's frag_align_pad setting was missing,
leading to misaligned access to the skb passed up
to the stack.

I have tried this in a tree I have, and where I was once seeing unaligned access
messages on an ia64 system with LRO enabled, now I see none.

Hi Dave,
The patch is intended for 2.6.29, not 2.6.28 as the subject mistakenly
states.
Cheers,
