Description

From Sebastien Roy's original bug report at Delphix:

Whoever introduced this tunable neglected to test its functionality, as the
initial low watermark for new connections doesn't take it into account.  The
initial setting of conn_sndlowat should verify if this tunable is non-zero, and
use it accordingly.
