NIC Driver source availability

Hello,
Just wondering if there is any source code available for 3Com 905 NICs,
or if it will be made available sometime. I am interested in a way to
directly access memory on the NICs buffer for high speed traffic analysis
applications.

devn-el900.so was written under NDA so it won’t be released in source form.

However, you really don’t need the source to any driver to what you want to
be doing. All of the “smart” cards that can do bus mastering DMA (tulip,
speedo, etc) copy data right into the packet buffers. So if you make
yourself an en_en filter and plug into io-net you will get a pointer to
the packet data directly as the packet goes up thru io-net.

Thanks,

But, what I meant was how do I do it from my program?
