I've been able to test the netbsd-INSTALL_OCTEON installer now, with my
addition of the bpf device to the image. With evbmips-mips64eb dhcpcd
now works, though with evbmips-mipsn64eb we run into a different
problem, which I'm still looking at. I've requested a pullup of this
to the netbsd-10 branch, along with some other additions to allow that
ramdisk to work with GPT wedges, should someone use the octeon.img
image, then find the need to recover the resulting installation. (Which
has already happened to me twice -- that is, I place a copy of
netbsd-INSTALL_OCTEON on the boot wedge, so I can boot into that and
recover rather than going through the trouble of removing the USB stick
from the machine; I'd done that in my initial setup, then discovered I
couldn't inspect or mount dk1 the first time I tried to recover!)
