I doubt it. I did some work[1] on the vr driver on a pcengines ALIX, which has very similar hardware (500MHz Geode CPUs and VT6105M ethernet chips). The most I got though it for a TCP stream was 85MBit/s routing only. It had CPU to spare, so I suspect the limitation was either the chip or the driver. The VT6105M doesn't have any receive-side interrupt mitigation (and OpenBSD doesn't have a polling mode) so I suspect it'd be easy to DoS it with tiny packets. As long as that's not happening, there's probably enough CPU to run PF. Depending on your use case and environment this may or may not be good enough. If you do try it I'd be interested in hearing the result.
