From 97064ad88123744056d141e96247348dd2d9621c Mon Sep 17 00:00:00 2001 From: Mark McLoughlin Date: Fri, 7 Aug 2009 09:39:51 +0100 Subject: [PATCH] net: fix vnet_hdr bustage with slirp slirp has started using VLANClientState::opaque and this has caused the kvm specific tap_has_vnet_hdr() hack to break because we blindly use this opaque pointer even if it is not a tap client. Add yet another hack to check that we're actually getting called with a tap client.
