I found my answer: probably all old frame formats are still being used, and
the newest
Ethernet spec is backwards compatible with most of them.
And due to the desire to tunnel through existing networks, or create new
kinds of networks,
the number of combined, or new packet types is always increasing.
The world of Gigabit ethernet protocols is so wide it almost makes the SI
part look easy
(at least until one mentions PAM4 modulation....)

Subject: [SI-LIST] GbE LLC/SNAP
I apologise for being a bit off-topic, but I don't know where else to ask
questions about current implementations
of Gigabit Ethernet.
Does anybody know of an email reflector for current 1 Gig and 10 Gig
Ethernet developers?
I am working with Gigabit Ethernet serial links and I am wondering about the
variety of ethernet packet formats.
The latest version of IEEE 802.3 seems to have dropped support for the
802.2/802 LLC/SNAP frame format,
and the LLC/SNAP standards have elapsed (have not been updated in over 5
years).
Can anyone comment on this, can I assume that new developement work
therefore has no LLC/SNAP packets?
Or do old ethernet frame formats never die?
Sincerely,
