June 29 6:45 PM:

Current status: Up until now, I have completed most of the data structure definitions, skge_probe(), and skge_open(). I am obviously quite behind compared to my project plan, but that is not something I can easily resolve; However; It does look like I will have time still left over at the end of writing the skge driver for some other prospects in this task. Possibly tg3?

So, after basicly 3 days off (except for a little work on saturday during and after my meeting) I'm ready to get going. It's 6:47 PM and I'm about to start on skge_transmit().

June 29 2:00 AM (really June 30):

It's been a productive night; I discovered and fixed another memory issue with the allocation of Adapter; Once that was dealt with, I implemented skge_transmit and skge_poll. I'm not certian as I haven't setup wireshark yet, but I believe that I just saw my skge driver transmit it's first packet.

I also pretty much overhaulled the DBGP commands so that anyone interested in writing a driver can literally just look at the output and understand all that is going on.
