Hi Johannes and Richard,

Thank you for your work and great comments.

For the S-MPDU issue, S-MPDU is same as VHT single MPDU in 802.11ac.
If there's pre-defined field for VHT single MPDU, we could use that.

For the S1G NDP issue, I found that there's PHDR_802_11_SOUNDING_PSDU 
for "0-length PSDU" field. That sounding PSDU means NDP sounding frame, I guess.
So I think we could add S1G NDP frames under "0-length PSDU" field.

I will look at the other comments separately, but I think Aggegration relates to A-MPDU if I am reading section 9.7 of 802.11ah-2016 correctly.

In which case, we already have an A-MPDU header but we might need some changes. Perhaps the WFA folks or Aaron can comment on this/
