 Note that although this is a little surprising initially, it could well 
 be intentional. For comparison, SIOCGIFNETMASK has the same behaviour on 
 other platforms that have sa_len, including Darwin and AIX, so FreeBSD's 
 behaviour is in line with other implementations. Changing the behaviour 
 of the ioctl might break someone's code.
