Seems like it.

Given that 80-column real-estate is precious and we're likely to have more
valuable on/off things to display in the future, it might make sense to
define a FLAGS field akin to file permissions with `ls' which would either
have "p" or "-" depending on whether promiscuous mode is enabled.  We've
done this already for other dladm subcommands; ipmpstat and IPS's pkg also
do this.
