Ethernet over SpaceWire-software issues

Issues that will be addressed here, to allow Ethernet to work over SpaceWire, include: converting Ethernet addressing into SpaceWire routing; behavior in the event of faults (which may create a need to re-route); handling broadcast; and considering whether the network topology is static (as in conventional large spacecraft) or dynamic with plug and play (as suggested for responsive space on small satellites, or for the Shuttle/CEV).
