I too see the 4 byte bug, this time with dhclient. The message reads: =
"ip length 328 disagrees with bytes received 332." This is causing =
other problems too. One note in the archive included a possible =
solution, which is pasted below. Has this batch made its way into the =
source? Please reply if you've used this patch either successfully or =
unsuccessfully.
By the way, my platform is 2.2.16.

I have a solution to the problem. By changing the following lines in the
rtl8129_rx funtion (around line 1260):
#if 1 /* USE_IP_COPYSUM */
eth_copy_and_sum(skb, &rx_ring[ring_offset + 4],
rx_size, 0);
skb_put(skb, rx_size);
#else
to
#if 1 /* USE_IP_COPYSUM */
eth_copy_and_sum(skb, &rx_ring[ring_offset + 4],
rx_size - 4, 0);
skb_put(skb, rx_size - 4);
#else
This removes the 32 bit status word from the packet data. =20
