		rscheffUnsubmitted Not Done Inline Actions This won't actually change the absolute minimum. Only the default minRTO (which is exposed as sysctl nowadays). Still valuable to make sure minrto doesn't fall below 2 or 3 ticks (there are no such precautions in the current stack, other than rto_slop) rscheff: This won't actually change the absolute minimum.
