bwfm(4) is working for me, but when in device tree mode (wherever the
uSD is routed) bse(4) is flaky - ethernet link doesn't come up at boot,
if I leave it for a little while with a ping running to the bse from
another machine I get the occasional packet through but that's all.
Do you see that too?
