We currently suggest customers use a Linux server to ping against, or another public host. Ideally we'd like to use a hardware based ICMP system for customer use - Accedian NIDs are good at this (exceptionally low jitter) accept they throttle at 500 pings per second.I know that the NETNOD folks did NTP in a FPGA that can do 4x 10GE, perhaps that card and code could be used to do 40G ICMP responder?
or, alternately test some useful application instead? I mean, 'wget' will tell you stats about the bw/etc... apache-bench will as well, and you can probably whip up some custom python/etc that'd do the same sort of thing.
