stdout/stderr; xm then spawned vncviewer (which never closed its
inherited stdout and stderr); xm then would exit, but YaST still had
open file descriptors, and therefore waited forever.  It would be

[NET] front: Check for received packets in network_open0

Because the backend brings up the interface long before the frontend
has booted up, it is possible that by the time we get here we already
have packets queued up for processing.

If we don't process them here, we may delay them more than what is
necessary.  Worse yet, it is possible to miss the notification
interrupt from the backend in such a way that we never get another
one until we bring the interface down and up.
