Subject: Allow the cloning /dev/tap interface to be used on FreeBSD and NetBSD.
X-Git-Tag: release-1.0.10~4
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=ec4c8bcb18c1f463cf4544126e027fc8ec9b3a39

Allow the cloning /dev/tap interface to be used on FreeBSD and NetBSD.

This device works like /dev/tun on Linux, automatically creating a new tap
interface when a program opens it. We now pass the actual name of the newly
created interface in $INTERFACE.
