Nick.

You may have compiled this, but it's obvious you
haven't tested it.

Please stop sending patches until you can verify what
you're doing with the code.

Please train a few more of your neurons for coding.

It takes some time and some practice but please don't
practice on linux-kernel.

Use google to find some other suitable forums like
http://cboard.cprogramming.com/c-programming/

Back to your patch:

	if (!skb)
		return false;

must go _after_

	skb = dev_alloc_skb(frag_length + 4);
