I bought an USB-Ethernet adaptor from delock (www.delock.de) and found it was
not supported by linux from the vendor. So I played a little with lsusb and
found it uses a MCS7830 chip from MosChip semiconductor (moschip.com). On
their homepage I found a driver but it only was a precompiled Fedora4 module.
So I wrote them an email and they sent me the whole source code for the
module . Unfortunately it doesn't compile on my machine with a 2.6.16 kernel,
but in does on a friend's one who uses 2.6.12, so I assume something has
changed in the kernel interface (I get errors with sk_buff_head not
containing "list").
I have no idea of how to correct this but maybe someone else can. I attached
the sourcecode wich is licensed under the GPL.
Great. below is an UNTESTED patch which should get it to build fine
with more recent kernels. (Builds on 2.6.17-rc3). Give it a try if you
can and let us know.
