Comment 36 for bug 659143

@Wolfgang:

I'm attaching my v2 patches. I added a patch to check the return from
skb_pad(). As part of this I moved the skb padding to the start of each
function, as I would assume we should bail before doing any other device
accesses if we can't get the memory. Let me know whether or not the
behavior looks correct to you.

I've uploaded the test build with these patches to:
