Ummm, nope.  The PSC guys who did lots and lots of the early work on 
SACK used NetBSD for much of their stuff, and the patches are probably
still available.  This was back in the NetBSD 1.3 timeframe, so it'd
probably be challanging to port to NetBSD-current.  I had these patches
working at one point and they seemed to work fine.  I don't think that
they were really ready to be imported as-is, though.  See:

NetBSD 1.6 does support adjustable initial window sizes and New Reno.
