SO_BINDTODEVICE

Tue May 10 15:13:10 UTC 2016

My device has multiple interfaces and supports dynamic ips.
SO_BINDTODEVICE looks like it would be used to specify a device in the
listen statement instead of having to update every IP change.

I see someone submitted a patch years ago that wasn't accepted and
there was no follow on. Is there any particular reason other than this
probably isn't a common use case? Is this something that could be
added in the future?
