As far as I can see, the two stable attributes, however, are the "Ethernet" name and the frame format.
I therefor assume that the 100G Ethernet frame format will look as follows.
The figure not only shows the standard frame but also the tagged version.
I expect the QoS priority bits marking to remain stable as well.
To my understanding, the speed increase to 100 Gigabit Ethernet will not result in any changes to the structure and handling of Ethernet frames.
