[AX210] How to capture 11ax trigger-based packets with AID

[SOLGIL]

Hi

As of now, I am able to capture 11ax SU packets (including full data packets) with the AX210 on Ubuntu 20.04 (kernel 5.15).

Going one step further, I am checking how to capture 11ax MU Trigger-based packets for the target Association ID. Could you let me know how to set the target AID to iwlmvm ?

I have read some post that the target AID can be set with the command below: 
  $ sudo echo <AID>  <AP/BSS MAC>   >    /sys/kernel/debug/iwlwifi/*/iwlmvm/he_sniffer_params

Unfortunately, when I try this command on my Ubuntu 20.04 machine, 

it showed "Permission denied" error message even though the command was excuted by root.

Did I miss something or do we have another way to give target AID information to iwlmvm ?
