[c-nsp] Cisco 2811 performance issue - dual(new) isp

The fa0/1 interface literally plugs into the cable modem for the ISP. Do
you think I should increase the buffer size a bit for that interface? I'm
sure there is a command for that. I added another  "sh int" and the full
"sh buffer" output near the bottom of this message.
