Dear Patrick,
Below is my try to add vlan-id 24 on eth1, followed by "ip -d link list":

You're apparently using the "VLAN_NAME_TYPE_PLUS_VID_NO_PAD" naming
policy, which causes name clashes when you create two VLANs with the
same ID.

I'd suggest to use iproute to create the devices, which allows you to
specify the desired name manually. Alternatively you can use vconfig
and a different naming policy.
