Looks like someone's running jumbo frames.

Yep -- for about 15 years maybe? For some reason
it seems to involve maybe ~1/6th the normal
packet overhead.... ;-)

eth0+eth5 use the bridge (internal house net),
while eth2 is an outward facing Iface. It will likely be
a while before my outward facing Iface needs the same
efficiencies I strive for on my internal net.

Good eye!
