I found a workaround (kind of), see below.

[ snip ]

With command 'etherswitchcfg port0 addtag pvid 1', config for port 0
becomes

port0:
	pvid: 1
	flags=5<CPUPORT,ADDTAG>
	media: Ethernet 1000baseT <full-duplex>
	status: active

and _all_ frames sent to CPU have dot1q header. This way I can create
up to 16 vlan groups on etherswitch (and correspondign arge1.n
subinterfaces) to achieve what I usually want, just one thing seems not
to be possible this way - hybrid port with both native (untagged) and
tagged traffic.

In any case, it would be good to have this better documented. I don't
know if we have any place for this. man page is good, but not
everything did work for me.
