YEs layer separation, but there are interfaces between layers, right?

I mean, if RFC8691 specifies that the MTU must a be of a minimum
1280bytes, then the MAC should satisfy that by fragmenting and
reassembling where necessary, if necessary.

If RFC8691 says that the frame format below IP must use QoS Data headers
then 802.11bd wouldnt say otherwise.

If RFC8691 says that the priority value must be '1' in the QoS data
header (at the MAC layer) then 802.11bd wouldnt say otherwise, right?
