XTC, it's not your config.

I have just googled around and happened to find a fix for a recent linux kernel where they fixed the MTU. They said that a packet larger than 1486 bytes didn't go through earlier because it overwrote the header or something. So this is one thing that is most probably wrong.

The other thing I googled up is that another guy reported that as long as the device autoconfigured to 100 Mbps it didn't work. He said he had to patch the driver to set it to 10 Mbps only and then it worked. Interesting.

Is there a source code for the usblan package somewhere? I'd like to compare the dm9601 driver source and possibly build a modified one.
