From aa4f082f7526d39dac8e2ca64d192d858014ee10 Mon Sep 17 00:00:00 2001 From: Brad Smith Date: Sat, 3 Aug 2013 22:20:41 -0400 Subject: tap: Use numbered tap/tun devices on all *BSD OS's The following patch simplifies the *BSD tap/tun code and makes use of numbered tap/tun interfaces on all *BSD OS's. NetBSD has a patch in their pkgsrc tree to make use of this feature and DragonFly also supports this as well.
