Most network cards have supported direct vs. crossover detection for a while, so that shouldn't be a problem. What likely happens here is that when DHCP fails, the OS assigns a IPv4 Link-Local address, which presumably the network drive also does, and they can talk on a LL network. We used to have automatic functionality like that in NM, but people got really confused as to why NM said they were connected to the Internet when they really weren't. But that was long ago and we could probably figure out a better behavior here. As in, really, this should only happen on wired networks, and even after assigning a LL address we should periodically retry DHCP just in case you're connected to a real network but the DHCP server went down for 5 minutes. Something like that. But currently it's not automatic since doing this breaks a bunch of other use-cases.
