From 9f8b97f888445b737ea3716ca53498663e18d971 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 17 May 2015 21:45:01 +0200 Subject: [PATCH] fakelb: don't deliver when one phy A real phy don't transmit the transmitted frame back to the phy. This behaviour will confuse the 6LoWPAN and the upper IPv6 neighbour discovery cache. We need now at least two virtual phy's to creating a virtual wpan network.
