With the patch running against linus's git tree, my box locks
up. You cannot ping it. I do not get a oops or anything in the logs,
and the keyboard does not respond. I will try to get some oops
output and more info.

Herbert, any idea offhand?

Yeah, I missed an offset update in there :) Here's a better version.

net: Fix frag_list handling in skb_seq_read

The frag_list handling was broken in skb_seq_read:

1) We didn't add the stepped offset when looking at the head
are of fragments other than the first.

2) We didn't take the stepped offset away when setting the data
pointer in the head area.

3) The frag index wasn't reset.

This patch fixes both issues.

1-3 (both, :-)) doesn't seem to work here, I applied this and still got a 
panic when doing a quick test before I went home today.

I can get panic trace from netconsole tomorrow.
