I am working on a system that has a stable MACaddr (an issue with many
arm SOC), so I don't suspect that as an issue.

Note I have set up the switch port so that ALL my vlans are accessable
from this port as 'tagged'.  There are no 'untagged'. VALN 16 is one of
the available labels.  I had earlier tried this with only VALN 16
available, and that did not work; I enabled all vlans then. None of the
vlans are untagged, so nothing is reachable the eth0.

It bothers me that eth0.16 does not even show in the 'ip addr show'
command output.

Have you verified that the driver for that NIC supports VLAN tagging?
Some don't.

Looks like I am going to have to ask on the Fedora-arm list:

vconfig add eth0 16
WARNING:  Could not open /proc/net/vlan/config.  Maybe you need to load
the 8021q module, or maybe you are not using PROCFS??
Added VLAN with VID == 16 to IF -:eth0:-

ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

ifup eth0.16
Error: Timeout 90 sec expired.

So the vconfig command did something, but not enought.

You may need to load that 8021q module. Check with "lsmod". If it's
not there, try "modprobe 8021q".

Have you tried a manual config, e.g. "vconfig add eth0 16"? If that
works, could you add

    KERNEL="eth*"

to the line in your /etc/udev/rules.d/70-persistent-net.rules file and
see if that helps? It may be that the kernel isn't recognizing the
device's name.

More work to do...
