Any ideas on how we can verify what the speed really is? Since they are
seeing this number - there is now doubt in the air :-)

Decent performance tools can be used to benchmark it. Create a benchmark from
one linux
server to the other and measure it.

Right -- that was step 2 -- I was hoping there was some Redhat command that
could tell us (one that works on s390x distros) ...
Thanks, Barton -- we'll see what we can find out thru our own measurements..

Thanks, Bruce -- we did that and confirmed it's set to gigabit.. but there
seems to be concern from the Linux folks as mii-tools is reporting 100mbs
and ethtool is not reporting anything...

I'd actually argue that ethtool is right -- there really isn't any valid
number TO report. Reporting
