Re: [libvirt] [PATCH v2] util: only register callbacks for CREATE operations in virnetdevmacvlan.c

From: "D. Herrendoerfer" <d.herrendoerfer(a)herrendoerfer.name&gt; currently upon a migration a callback is created when a 802.1qbg link is set to PREASSOCIATE, this should not happen because this is a no-op on most switches, and does not lead to an ASSOCIATE state. This patch only creates callbacks when CREATE is requested. A VM restore also leads to an association creation and it is also covered here. Migration and libvirtd restart scenarios are already handeled elsewhere. Signed-off-by: D.
