OID_GEN_CURRENT_LOOKAHEAD (Windows Embedded CE 6.0)

1/6/2010

This object specifies the number of bytes of received packet data that will be indicated to the protocol driver. This specification does not include the header.

For a query, NDIS returns the largest lookahead size from among all the bindings. A protocol driver can set a suggested value for the number of bytes to be used in its binding; however, the underlying NIC driver is never required to limit its indications to the value set.

If the underlying driver supports multipacket receive indications, bound protocols are given full net packets on every indication. Consequently, this value is identical to that returned for OID_GEN_RECEIVE_BLOCK_SIZE.
