Some new findings:
- I've added a print of the skb->data_len and skb->len sizes right
before the BUG_ON line.
skb->data_len was always 0, so I don't understand why there is a kernel panic.
- It's unnecessary to use netperf to reproduce the bug.
It can be reproduced just by copying a file between 2 hosts with scp.
- I removed the BUG_ON line and copied a large file between two hosts.
The file got to the other side without any corruptions.
