About a year ago I wrote a patch which makes it possible to add ‘descriptions’ for network interfaces. You can read the details in kern/83622. Today I’ve updated the patch and submitted follow-up to PR. It’s sad that nothing moved towards committing it. Although this feature is very useful for me. On one of the boxes at work we have:

r1[~]# ifconfig | wc -l
513
r1[~]#

It’s almost impossible to keep all that stuff in the head and being able to set description is very nice. It would be sad if I had to maintain this patch out of the tree…
