--- Comment #24 from Kevin Bowling <kbowling@freebsd.org> ---
(In reply to pascal.guitierrez from comment #23)
Thanks for reporting back.  That is very interesting.

There are two possibilities that come to mind 1) the RACK stack is correctly
identifying the loss as feedback for it's flow/congestion control or 2) the
RACK stack has some feature that is causing it to not overflow the lower
layers.

I'll see if I can find someone with more recent TCP stack experience to gla=
nce
at this and provide any additional insight or suggestions for the base stac=
k.
