This would put the contents of an Ethernet frame inside of an IP packet, therefore not having any special requirements for the network that will be transporting the encapsulated frames. For example, suppose you had a "gateway" on each end with both a wireless and an Ethernet NIC. For each gateway, the Ethernet NIC is in promiscuous mode. The contents of each frame that is received from the Ethernet will be put in an IP packet and sent over the wireless connection. The other end would take the frame that is contained inside of the packet and send it out on it's own Ethernet. You now, essentially, have bridging over the wireless connection. I'm not sure how much sense this makes, but the IETF drafts can probably explain the concept better.
