FWIW, I believe SMBv3 is just a set of (largely optional) extensions to SMBv2,
not an entirely different protocol, like SMBv1 is.  Which means, any version
that supports v3 is likely to also handle v2.

There seems to be existing, working code in Nexenta, which is being
upstreamed to Illumos:

https://www.illumos.org/issues/9735
https://github.com/illumos/illumos-gate/pull/37

Their implementation descends from the one we have in base (and the one
from OSX, which also descends from FreeBSD), so it should be possible to
merge it.
