# TODO: at time of writing, ntb on SCALE has pathological
# behavior related TCP/IP Window size calculation whereby
# the receiving side clamps the window size to 0 causing
# recalculation which, ultimately, ends with behavior
# described in https://en.wikipedia.org/wiki/Silly_window_syndrome
# The work-around is to drop MTU size a bit which fixes
# the scenario altogether. When we discover why this is
# happening, we should remove the MTUBytes line.
