From 0f850909c83852a4c230b6ec73def7f33f4808ad Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Mon, 7 Feb 2011 16:55:25 +0000 Subject: [PATCH] tools/hotplug: set mtu from bridge also on vif interface Apply mtu size from bridge interface also in vif interface. This depends on a kernel change which allows arbitrary mtu sizes until the frontend driver has connected to the backend driver. Without this kernel change, the vif mtu size will be limited to 1500 even with this change to the vif-bridge script.
