I found the problem:

if (skb->xmit_stamp) {
rtos_get_time(&time);
rtos_print("xmit_stamp=%#Lx -> ", *skb->xmit_stamp);
*skb->xmit_stamp = cpu_to_be64
rtos_time_to_nanosecs(&time) +
*skb->xmit_stamp);
rtos_print("%#Lx\n", *skb->xmit_stamp);
}
/* Push the data cache so the CPM does not get stale memory

*/
flush_dcache_range((unsigned long)skb->data,
(unsigned long)skb->data + skb->len);
The "flush_dcache_range" was before modifying skb->xmit_stamp. I was not
aware, that it's pointing to skb's data :-(.
...and as the packets were sniffed on the sender side, the correct copy
made it into the dump. Fine, another problem solved. :)
Then please let me know when your tests with the new driver run fine so
that we can roll out a 0.8.3. With the upcoming official RTDM, we need
some reorganisation work (=>0.9), and I would like to have a cut first.
