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

Isn't CWmin and CWmax only used for retries?

No.

We recently had the problem that on 5MHz channels probe-responses of
APs which can't hear each other (hidden node problem) always collide.

I think this is what I neglected - if the APs won't hear each other,
all their own sensing and NAV won't help since it'll never be updated.

CWmin/max are short enough to not actually matter in this case since
they're not long enough to avoid colliding entirely even if one picks
the lowest and the other the largest possible value.
