RE: [PATCH v2] mac80211: Jitter HWMP MPATH reply frames to reduce collision on dense networks.

quoted

Well it certainly attempts to via stuff like carrier sense. But that
is not fool proof and any time two routers hear a frame and both
decide to forward it immediately there is a chance that they will both
sense the air at the same time, decide that it is clear, and lose both
their forwarded frames due to a collision. How often that happens is
hard to say but we have observed that exact behavior a few years ago
with an 802.11 multicast routing protocol and adding jitter
significantly improved reliability.

I'm really surprised by this since they both should jitter their
transmissions
already between CWmin and CWmax. Is that window somehow really super
small for what you're doing?

I don't think so.
