When you see the [|xxx] syntax in tcpdump, that is its way of telling
you that the packet you captured is truncated, and it cannot show you
more information unless you capture a longer packet.

With recent changes to PF, the default capture size (68 bytes as seen
above) is insufficient.  Try adding "-s128" to capture more of the
packets and you should see an improvement.
