At long last discovered (accidentality) what causes the loss of 
connectivity when enabling vlan_filtering, the node being dual-core and 
each core providing a port facing the switchdev:

cpu0 - eht0 [RGMII] <--- > switchdev port 6
cpu1 - eth1 [RGMII] <--- > switchdev port 5

If only one of the CPU ports is connected to the respective switchdev 
port connectivity to the node gets severed when enabling vlan_filtering.
With both CPU ports connected to the respective switchdev ports 
connectivity remains uninterrupted to the node when enabling 
vlan_filtering.
