OID_GEN_CO_PROTOCOL_OPTIONS
A bitmask that defines optional properties of the protocol driver. A protocol informs NDIS of its properties, which can optionally take advantage of them. If the protocol driver does not set its flags on a binding, NDIS assumes they are all clear.
The following flags are currently defined:
NDIS_PROT_OPTION_ESTIMATED_LENGTH
Indicates that packets can be indicated at the worst-case estimate of packet size, instead of an exact value, to this protocol.
NDIS_PROT_OPTION_NO_LOOPBACK
The protocol does not require loopback support on the binding.
NDIS_PROT_OPTION_NO_RSVD_ON_RCVPKT
The protocol does not use the ProtocolReserved section of indicated receive packets. This allows NDIS to indicate a receive packet to more than one protocol.
