Haaaahahaa... so the 3750 has the same issues the 2960 has - if you
turn on "mls qos", the tiny buffers get reduced to tiny/4 buffers,
which makes the drops show up much earlier. And we also ran into the
"older IOS versions just don't show the drops".
(Yes, of course we tried whether turning on mls qos would help us in
any way - it did, it made the issue much more prominent... :-o ).
