tcpdump would display

We have lots of trace sources in the various net devices in the system, and we
hook these traces into what we advertize as a pcap trace output. In some
cases, we just kindof fake it. For example, in the CSMA device the transmit
event is hooked into the transmit queue Enqueue event, which can give
misleading results. This situation should really have a dedicated low level Tx
hook symmetric with Rx.
If we're going to advertise pcap traces, they should really work like one would
expect -- consistently across the devices.
