When an interface name has been omitted, the lnet would iterate over the list of system IP interfaces (by SIOCGIFCONF) and choose the 1st one whose status is "up" (SIOCGIFFLAGS) and has been configured with a valid IP address (SIOCGIFADDR). If that 1st interface happens to be 'eth0', then it's equivalent to explicitly setting interface like: > -- > options lnet networks=tcp0(eth0) > -- Apparently, in the 1st configuration, 'eth0' is not always the interface picked by lnet - 'eth0' could not have been configured an IP address, and there could be other IP interfaces (e.g. IPoIB) that come ahead of it.
