From 82e56b6b7c05eebc589b37e96ed3b0a44d6cdef7 Mon Sep 17 00:00:00 2001 From: Chris Friesen Date: Thu, 12 May 2016 18:00:00 -0400 Subject: [PATCH 05/10] Make kernel start eth devices at offset In order to avoid naming collisions, we want to make the kernel start naming its "ethX" devices at eth1000 instead of eth0. This will let us rename to a range starting at eth0.
