7.99.71 is the most recent kernel ABI version (NetBSD-current).

Release engineering builds of NetBSD-current are hosted on nyftp.netbsd.org.

kernel:

http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201705170540Z/evbmips-mips64el/installation/

installation medium:

http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201705170540Z/images/

[In future there will be need to switch 201705170540Z to a newer
snapshot, as this one will be removed.]

I will have to a look tonight and try to reproduce locally (and take
MIPS 64-bit crash course).
