Once again this list comes through with blinding speed. I had 9
responses to my question before I even saw the question show up
in my mailbox.

The answer to my problem is that you have to "plumb" the interface
before you can do anything else, by typing "ifconfig qe0 plumb".
Things would also have worked if I had blindly assumed that the
card was functional and had created a "/etc/hostname.qe0" file
and had let the system configure the interface during the boot

Many thanks to the following:

Original question:

> Help!

> ifconfig: SIOCSIFFLAGS: qe0: no such interface
