Hi,

from what I see, plasma-networkmanager uses the "Connection name" also
as the interface name and so there are some extra restrictions on the
name.

It doesn't seem possible to have different interface and connection
names; this is a limitation in plasma-networkmanager because
NetworkManager allows that. Please file a bug on the KDE issue
tracker.
