$NetBSD: patch-tuntap__freebsd.c,v 1.1 2014/04/04 13:48:34 phonohawk Exp $

Hunk #2: FILE* fd will never be < 0.

Hunk #1, #2: tuntap_open() is calling a wrong function, leading to a
         linkage failure. This bug goes unnoticed if you are using GCC
         because the call of tun_close() is optimized out as the
         condition "fd < 0" never holds.

TODO: This patch should be sent to the upstream.
