(Moderately informed FUD follows)

I believe, that the original "tuntap by Maxim Krasnyansky" was made
primarily for BSD/Linux, and needed some developer love to work under
Solaris.

http://vtun.sourceforge.net/tun/faq.html
http://vtun.info

One project of "Solarisizing" the tuntap was Kazuyoshi's work:
http://www.whiteboard.ne.jp/~admin2/tuntap/

He also made (and ultimately RTI'd) some tweaks for OpenVPN.

Last summer he also "Improved throughput perfomance by increasing
q_hiwat of read side stream head queue" which boosted my TCP IO's
(like CIFS over OpenVPN) by about 5-7 times, and this is the build
version supposedly present in the repository.

Now, I don't really know now which code is in which repo, but they
both come from same roots; it may also be possible that the original
project borrowed some improvements from this branch. I haven't used
"Maxim's tuntap" with Solaris at all, so can't comment on it more.
