Hello everyone.
I have developed a Windows NDIS Miniport Driver for a network card. Now
i want the same driver to be ported to the MAC OSX 10.4.3.
[...] One of the document on www.apple.com/mac/ tells that there are 3
options
1. High level API to access the hardware from the app side. Here we can
skip the driver.
2. Application driver.
3 Kernel drive.
And one more thing is that KEXT (Kernel extentions).
These all things are adding comfusion in my mind, The picture is not
very clear. What option should i choose? Please tell me how can i
proceed so that i can complete the task of developing the network
driver.

If your network card is anything like a normal network card (high
throughput, often used, by many applications), you should use option 3,
a kernel driver. On Mac OS X, 'kext' or 'kernel extension' is where
third party kernel drivers (and many, if not all, Apple-built drivers)
live.

Useful starting points are
<http://developer.apple.com/documentation/DeviceDrivers/index.html> and
(slightly more specific)
<http://developer.apple.com/documentation/DeviceDrivers/Networking-date.h
