It's just that the layers above > the fundamental physical layer are very, very different. 802.11 is multiple things, and IBSS is basically like 10base5/10base2. With BSS mode, you associate with an AP which is basically like plugging into a hub/switch. > The relevance here, I think is that if you're going to try to keep > 802.11 and Ethernet to a common framework, it needs to handle Ethernet > as well as 802.11, and Ethernet is a peculiar beast nowadays - it is > conceptually a shared medium, but recent implementations of it are > fundamentally interconnected-star topologies rather than bus > topologies, with a bus-topology fiction built atop the star reality.

It may be that with 10base2, "UP" means "cable is terminated properly". Or perhaps it's NA.
