Hello. I’m writing Network Driver. I implemented Power Management indication capabilities which supports Apr Offload. I added *PMARPOffload key. And driver doesn’t get OID_PM_ADD_PROTOCOL_OFFLOAD although when the system goes to low power mode NDIS tries to enable ARP offload in OID_PM_PARAMETERS . Does somebody know all conditions which are needed NDIS to send OID_PM_ADD_PROTOCOL_OFFLOAD ?
