From: Olivier Martin <[email protected]> When Arp driver starts (with ArpDriverBindingStart()), its service will be created and the Mnp child configured (ArpService->Mnp->Configure() called in ArpCreateService()).
It is only at this time the Snp protocol will be initialized (at the end of MnpStart()). So, a valid SnpMode could not be expected prior to ArpService->Mnp->Configure().
