I had assumed I would be able to use the existing pf.conf (which has worked for years) even after the introduction of the vlan2 interface as the pppoe0 parent. To get anything to work I had to remove all queueing references.
BTW, I am running 6.5: # uname -a OpenBSD malkmus.xx.xx 6.5 GENERIC.MP#3 amd64 Thank you for any suggestions to try. -felix
