Networking failed after image-update
Several network services including nwam, physical and netmask remained
in maintenance state after doing image-update.
Also the ifconfig command would not work and the network card could not
be activated using the network applet.**

Unfortunately I have installed OpenIndiana over the OpenSolaris system I was having problems with, so I can't provide the output you are asking for. The good news is the fresh install worked perfectly and all services are working.
The ifconfig command output something like it couldn't connect to a socket. It wouldn't even display any of the network interfaces on the system, so I couldn't configure any of them.
I'll upgrade another OpenSolaris system to OpenIndiana, and I'll advise if I have the same problem.
