Hi,

I recently added support to ath10k, for the QCA6174, to receive 
multicast action frames in order to support DPP. I'm trying to do this 
for the ath11k QCNFA765/WCN6855. I took the same approach as ath10k 
which was actually quite simple but I'm unable to see any multicast 
frames coming over even when I enable RX/DATA debugging.

What I've done so far is:

  - Add FIF_MCAST_ACTION to the supported filters list

  - Created/started a monitor vdev from within 
ath11k_mac_op_configure_filter()

     ath11k_mac_monitor_vdev_create(ar);

     ath11k_mac_monitor_start(ar);

- Also tried adding

     ath11k_mac_config_mon_status_default(ar, true);

I can successfully create/start the monitor vdev. I see now as I'm 
writing this email that my specific hardware does not support monitor 
mode outright... Is this a dead end or is there hope with purely driver 
changes? or is it some filtering at the firmware level preventing this?

Thanks,

James
