I'm afraid I couldn't deduce anything from the response I got to this.
A tiny bit of the output in response to a google request:
---------------------------------------------------------
02:01:12.233334 IP (tos 0x0, ttl 64, id 29329, offset 0, flags [DF], proto TCP (6), length 889) mary.homenet.telecomitalia.it.52893 > bw-in-f101.google.com.http: P 3501233035:3501233872(837) ack 3394341790 win 209 <nop,nop,timestamp 1465672 2699557374>
02:01:12.334854 STP 802.1d, Config, Flags [none], bridge-id 8000.00:1d:6a:c2:f5:37.800a, length 35
        message-age 0.00s, max-age 20.00s, hello-time 2.00s, forwarding-delay 15.00s
        root-id 8000.00:1d:6a:c2:f5:37, root-pathcost 0
---------------------------------------------------------

I get the last message repeated endlessly,
while the google windmill goes round endlessly,
having output 5 responses to my query,
though it says it has sent 10 (out of 2 million or so).

As I said, the output of tcpdump does not mean much to me.
