This appendix describes the procedure for generating a stimulus driver to use in place of a normal 32-bit driver when testing promiscuous mode with bad packets. Since the Bad Packet Tests are only applicable to Ethernet, you only need to create a stimulus driver if the driver under test is Ethernet, the hardware supports bad packets, and you cannot use an NE2000 adapter. If you have an NE2000 available you may use the SCNE2000.LAN or SNE2000.LAN for testing. These drivers will be provided with the tests.
A stimulus driver is a driver that has been modified to be able to generate runt, jabber, long and very short packets; as well as to support the CRC and Length tests.
For your driver to work as a stimulus driver it must support raw sends and work with TCBs rather than ECBs. If your adapter is ECB-aware or doesn't support raw sends you will need to test using the NE2000 or else modify another driver for an adapter that has been YES CERTIFIED.
If for any reason the above options will not work for you, contact Developer Support for help.
