V3 have unconditional running script , v4 check for net->script before running script

If user not specify network type ethernet, assume that user
needs simple tap device created with libvirt.
This patch does not need to run external script to create tap device or
add root to qemu process. Also libvirt runs script after device creating,
if user provide it.
Difference with v3 that script runs only if it provided.

It seems like your MTA mangled the patch. Moreover, how is this different to v3 that I've sent?
