Ok. It would be good to have an answer to this, because one of the assumptions of that patch was that whomever sets DEI=1 doesn't get to complain that their packets are *actually* dropped :)
FWIW, if you do need to set up a reservation for traffic received on a port, section 8.6.3.3.15 Buffer reservation watermarks (page 817) should help with this: https://www.nxp.com/docs/en/user-guide/LLDPUG_RevL5.15.71-2.2.0.pdf
