What makes me wonder is that both pci0:6:8:0 and pci0:6:9:0 has no
I/O BAR. I never saw these kind of thing on rl(4) controllers.
And I can't explain how rl(4) could successfully map the I/O with
non-existing I/O BAR.
Anyway would you try attached patch and let me know whether it
makes any difference? Also add the following line to
/boot/device.hints to have rl(4) use memory mapped mapping.

hint.rl.0.prefer_iomap="0"
