Changes since v1: Only flush tx queue if interface is mesh mode.
  This prevents kernel panics due to uninitialized spin_lock.

When more than one station hears a broadcast request, it is possible
that multiple devices will reply at the same time, potentially
causing collision. This patch helps reduce this issue.

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?
