On http://docs.openstack.org/networking-guide/intro_basic_networking.html it says:
"In an Ethernet network, the hosts connected to the network communicate by exchanging frames, which is the Ethernet terminology for packets."
This is not entirely correct. "Frame" is the OSI terminology for a protocol data unit (PDU) on layer 2. "Packets" is the OSI terminology for PDUs on layer 3. Since the text leading up to the quoted passage is about the OSI model, its layers and how Ethernet may/does fit in there, and the entire page is about protocols on various OSI layers and intended to teach people about these, this difference in terminology matters and ought to be corrected.
Frames and packets are clearly distinguishable. Mushing their meanings and even implying they are the same thing does not help this article and can be confusing, as both, layer 2 and layer 3 are discussed on this page.

Makes sense. Much of this content needs help. :)
