I just realised that I didn't check xenbr0 as well as eth0:

root@bedbug:~# ifconfig xenbr0
xenbr0    Link encap:Ethernet  HWaddr 00:13:72:14:c0:51  
          inet addr:10.80.249.102  Bcast:10.80.251.255
          Mask:255.255.252.0
          inet6 addr: fe80::213:72ff:fe14:c051/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:12296 errors:0 dropped:793 overruns:0 frame:0
          TX packets:437 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:618757 (604.2 KiB)  TX bytes:49084 (47.9 KiB)

root@bedbug:~# ethtool -S xenbr0 | grep -v ': 0$'
no stats available
root@bedbug:~#

The value for "dropped" increases steadily.  This particular box is on
a network with a lot of other stuff, so it will be constantly
receiving broadcasts of various kinds even when I am not trying to
address it directly.
