Porting network adapter drivers to MDI 2

Porting network adapter drivers to MDI 2

SVR5 network adapter drivers are implemented using MDI 2 and later versions. SCO SVR5 2.0 DLPI drivers cannot be developed on SVR5 systems, although some will work on early releases of SVR5; see ``DLPI''. Drivers for network cards that use media types other than those supported by MDI can be implemented using the SVR5 DLPI interface. This topic does not address raw DLPI drivers although some of the material is relevant.

This chapter summarizes the work required to convert earlier SCO network drivers to MDI version 2:

MDI version 2 drivers can use DDI 7, 7mp, 8 or 8mp; for general information about porting drivers to DDI 8, see:

MDI version 1 is the interface used to implement network adapter drivers on SCO OpenServer 5. The MDI manual pages document both the SVR5 and SCO OpenServer 5 interfaces; detailed porting notes are included on the manual pages.

For more information about MDI interface versions, see ``MDI''.

Ported drivers should also adhere to the guidelines in:
