Is this referring to D6.2 Table 26-9 "Setting of the VHT Channel Width
and VHT NSS at an HE STA transmitting the OM Control subfield"?
If so, then what does the part of "at an HE STA transmitting the OM
Control subfield" do? Do we need to check it? That doesn't sound like we
should apply any changed logic to normal VHT STAs?
