Most calls.  I did find one place where NetBSD 5.2 and 9.2 appear to
require that sin_len be correct.  (I'm not certain, but I think it is
the sysctl used for IDENT lookups.)  There also is code in 9.2's
SIOCSIFADDR that appears to treat a zero sin_len differently from
nonzero (look for the string "sin_len == 0" in in_control0()).  And if
I could find two with fifteen seconds of grepping and a few minutes of
code reading, there are probably others.
