Hi!
Our build bot found a build error when building libVirt with -Werror
introduced in
b4f62abbf1191c8fbab3306b4bf2f2567e18067f
kvm/virtio: Set IFF_VNET_HDR when setting up tap fds
The attached patch kind of fixes the build error but I'm not sure, if
this is the final solution for this problem, though...
Ciao
Max
