Hi Mikael,
The idea to identity the kind of devices (hence any QoE) based on MAC address
(probably on the OUI part) has work for many years; but, now more and more OS
do MAC address randomization (cfr the MADINAS BoF at IETF-109), so, I am afraid
that this 'easy/smart' technique is a thing of the past... Or, am I missing
something ?
Regards

I'm not 100% sure I understand your question but let me write some text
and see if it helps.
In Sweden, ETTH is often delivered with an L2 switch of some kind, can be
media converter or just CPE. Into this, you can connect a router, an ATA
(PSTN box), a TV STB, and based on the MAC address and possibly the
contents of the DHCP request, you'll get different responses, possibly
even that the device reconfigures ports into different VLANs etc. The term
used is called "free seating" (I have no idea where this came from) and
the idea is to reduce customer support calls when customers plug in
equipment into the "wrong" port, so instead just let customers plug into
any port and it just works. The DHCP responses might also be different
depending on type of device etc.
We also have cases where you register your HGW MAC address in a portal and
depending on this MAC address, your HGW will either receive IPv4 GUA or
end up behind CGN. So this differentiation is done on MAC address. Don't
know if you consider this "part of DHCP request" or not.
