From: Michal Kazior <michal at plume.com>

Some time ago it was found some drivers are
setting their hw/ucode rx filters restrictively
enough to prevent DPP multicast frames from being

A set of patches was introduced to the kernel and
ath9k driver as well as hostapd, eg.

  a39e9af90 ("nl80211: DPP listen mode callback")
  4d2ec436e ("DPP: Add driver operation for enabling/disabling listen mode")

Turns out chirping was omitted. As such chirping
wasn't working on drivers with restrictive rx

I've found this while trying to get ath9k working
as a chirping STA Enrollee.

The problem wasn't seen on, eg. mac80211 hwsim
