Forgot to mention: What's also strange is that the VLAN ID is very high:
# 4.14.18-300.fc27.armv7hl, iproute-4.15.0-1.fc28.armv7hl ip -d link show eth0.101 | grep "vlan protocol" vlan protocol 802.1Q id 3069279796 <REORDER_HDR> ip -d link show eth0.102 | grep "vlan protocol" vlan protocol 802.1Q id 3068673588 <REORDER_HDR>
On older kernels this looks ok: 4.12.8-200.fc25.armv7hl, iproute-4.11.0-1.fc25.armv7hl: ip -d link show eth0.101 | grep "vlan protocol" vlan protocol 802.1Q id 101 <REORDER_HDR> ip -d link show eth0.102 | grep "vlan protocol" vlan protocol 802.1Q id 102 <REORDER_HDR>
Ideas?
Thank you.
Ciao, Gerhard
