ok, so if that is the allocation and we are getting 0-length PSDU,
then it means that I am sniffing with the wrong AID?

In practice then I will just need to select an AID to which data is
being sent and then I will be able to see the HE_MU Data?

My goal is to see DL OFDMA data in wireshark. Thank a lot for your help :D
