Problem depends on guest. Steps to reproduce on Ubuntu 14.04 64bit server kernel 3.19.0-28-generic and qemu-kvm.

* set up a guest with virt-manager and set up a virtio ethernet interface
* install FreeBSD 10.1 64bit as guest
* set up an usable IP address on vtnet0 (FreeBSD name of virtio ethernet)

Make some traffic and check dmesg. After some time "skb_warn_bad_offload" occurs in dmesg on host.
Problem does not occur if e1000 is used instead of virtio, as recommended for FreeBSD on kvm.
