Packet capture. Can I use tcpdump or other libpcap tools with TOE cards? Can the card do pcap in its own microcode? 2. Statistics. What statistics are available with TOE? I know the Chelsio card keeps all kinds of potentially interesting stats as will as the basic packet and error counts. Can these be made available to user code, management tools, and such stuff? 3. The Chelsio card has some very impressive, but as far as I can tell, undocumented capabilities for things like traffic shaping and policing. Any of these available? If these issues are handled correctly, this could be a network researcher's dream. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
