I understand the desire for consistency. It's a bit more work than I have time for today, but I agree it would be worthwhile to put more effort into this. But do we now modify every such ioctl handler in the kernel? Or is modifying ifconfig sufficient? We are more concerned about textual display rather than the kernel/userland ioctl boundary, correct? The option list for ifconfig is [-AaC]. Plenty of letters available. We could add: -P Show authentication details such as passwords (not displayed by default))
