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
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
Ported drivers should also adhere to the guidelines in:
