There are no per-vnet initialisors in the source tree at this time which run earlier than SI_SUB_INIT_IF. A quick audit of non-virtualised SYSINITs indicates there are no subsystems pre SI_SUB_MBUF that would likely be interested in registering a virtualised hhook point. Settle on SI_SUB_MBUF as hhook's per-vnet initialisation stage as it's the first overtly network-related initilisation stage to run after SI_SUB_VNET. If a subsystem that initialises earlier than SI_SUB_MBUF ends up wanting to register virtualised hhook points in future, hhook's use of SI_SUB_MBUF will need to be revisited and would probably warrant creating a dedicated SI_SUB_HHOOK which runs immediately after SI_SUB_VNET.
