OID_GEN_MAXIMUM_LOOKAHEAD (Compact 2013)

3/26/2014

As a query, this OID specifies the maximum number of bytes that the network adapter can provide as lookahead data. This specification does not include a header.

Remarks

NDIS 6.0 miniport drivers do not receive this OID request. NDIS handles this OID with a cached value that miniport drivers supply during initialization.

Upper-layer drivers examine lookahead data to determine whether a packet that is associated with the lookahead data is intended for one or more of their clients.

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