[nsp] GSR tunnel card

[Hank Nussbacher]

Based on:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s21/gre.htm

"GRE tunneling is enabled on the Cisco 12000 series Internet router using a 
tunnel server card. The tunnel server card is an Enhanced OC-48c/STM-16c 
Packet-Over-SONET (POS) line card with a new software image."

There is no "tunnel card".  There is:
OC48X/POS-LR-SC	  CONCATENATED OC48 WITH EXTENDED FEATURES LONG REACH	
OC48X/POS-SR-SC	  1 port OC48 POS Extended features	

But this card says nothing about tunnel features:

Any idea if this is the right card to act as a tunnel server?
