Miniport Driver Support for 64-bit Counters

All one-Gbps and faster connection-oriented miniport drivers must support 64-bit counters for the following statistics OIDs. In addition, Microsoft recommends that all 100Mbps and faster connection-oriented miiniport drivers support 64-bit counters for the following statistics OIDs:

OID_GEN_CO_XMIT_PDUS_OK

OID_GEN_CO_RCV_PDUS_OK

OID_GEN_CO_BYTES_XMIT

OID_GEN_CO_BYTES_RCV

Such miniport drivers can also support 64-bit counters for other statistics OIDs, such as OIDs that indicate transmit or receive errors.

System support for 64-bit counters is available in Windows XP and later versions.
