LinkSpeed

Specifies the speed of the link, in units of 100 bps. Zero indicates no change from the speed returned when the protocol called NdisRequest with OID_GEN_LINK_SPEED.

MaximumTotalSize

Specifies the maximum number of bytes per packet that the protocol can send over the network. Zero indicates no change from the value returned when the protocol called NdisRequest with OID_GEN_MAXIMUM_TOTAL_SIZE.

RemoteAddress

Represents the address of the remote node on the link in Ethernet-style format. NDISWAN supplies this value.

LocalAddress

Represents the protocol-determined context for indications on this link in Ethernet-style format.

ProtocolBufferLength

Specifies the number of bytes in the buffer at ProtocolBuffer.

ProtocolBuffer

Containing protocol-specific information supplied by a higher-level component that makes connections through NDISWAN to the appropriate protocol(s). Maximum size is 600 bytes (on Windows Vista)
