From 3d1af1df9762e56e563e8fd088a1b4ce2bcfaf8b Mon Sep 17 00:00:00 2001 From: Zoltan Kiss Date: Mon, 4 Aug 2014 16:20:57 +0100 Subject: xen-netback: Using a new state bit instead of carrier This patch introduces a new state bit VIF_STATUS_CONNECTED to track whether the vif is in a connected state. Using carrier will not work with the next patch in this series, which aims to turn the carrier temporarily off if the guest doesn't seem to be able to receive packets.
