How did you get to 81?
I calculate only 51, based on the assumption that we can only have
NSS==8. Even if you think NSS==16 (which I doubt), I get to 80 only?

I considered max values for NSS and RU Index Bitmask sub-fields in PPE
threshold field.
i.e. NSS=16, RU Index Bitmask = 0x11111 with this max PPE threshold info
sub-field length is 60 bytes
Max PPE thresholds field length = 4 bits (for NSS) + 5 bits (for RU
Index Bitmask) + 480 bits (PPE info) + 7 bits (PPE pad)= 62 bytes
EHT fixed fields length = 10 bytes
Max MCS-NSS Set field length = 9 bytes
So total max length would be 81 bytes
