Hi Toke, hi Jon,

IMHO RFC8325 and the whole WMM scheme clearly lacks data showing that is actually delivers on its promises. RFC8325 specifically seems obsessed in changing mappings such that PHBs align with the 4 WMM queues, instead of interpreting the fact that the apparent mismatch between what the IETF thinks about specific PHBs/DSCPs and how they are treated for most users, as clear sign, that reality does not care... (probably mostly driven by the elephant in the room, of DSCPs not being end-to-end).

I agree with Toke that allowing APs to steer specific DSCP use by applications seems taking an proven non-working idea to the extreme... (APs can already instruct stations on which DSCPs to map to which AC (see Felix's patch), which is not used that much, no idea why anybody thinks that allowing APs even more disruptive changes to end-point behavior is going to work any better).

P.S.: IMHO the biggest change might be the up-prioritisation of EF from AC_VI to AC_VO, and I am not sure that is a good idea.
