It's not clear to me what you mean by "collision"? Over the air the NAV
should handle the avoidance thereof, so I don't really see what this
does wrt. collisions?
Are these frames somehow duplicates? But I don't see any suppression if
you've already put a frame on the "jittered" list then it will never be
deleted from it again, so it doesn't suppress anything in that sense?
