June 22: 
I started out the evening of the 22nd working on a debugging issue...

I asked rwcr for some help and he gladly provided it. The issue of the night was debugging why open (or any other procedure) was not being called at all. 

rwcr showed me how to hook up to to a gdbstub with udp debugging and I inserted an rtl8139b into my testing machine. After a while tracing variables and stepping into procedures, I found (again, with much help from rwcr) that the reference to netdevice that I was returning to the core was infact a reference to the net1 device, rather than the actual net0 device. Hens, my open (and subsequent functions) were not called because the core was calling the functions of another driver!

After tracing through what I had written, i found that I was initializing netdevice[0] twice; once in probe, then again (unintentionally) in skge_initialize. 

Removed this instance, compiled, booted, and all of open's DBGP commands showed up on the screen. Yay. 

So, moving on, the current obstacle is that mac address appears to be broken again. I will figure out why this is broken again, however, I checked the rest of the variables being initialized in dbg and they all appear to check out! yay. I will be moving on to poll this week.

Unfortunately, today I came home and saw that my computer was frozen trying to enumerate it's RAM. After some basic troubleshooting and memtest x86, i found that my main desktop machine has some faulty ram in it. Hopefully I'll be able to replace the ram in store tomorrow... 4x 2GB sticks of corsair dominator 1066 isn't cheap...

All I'll be able to get done today (well, the rest of today) is finish this journal post. However, tonight I initialized a complete build/test environment in my laptop and downloaded my git tree there. Hopefully this will allow me to continue to work and minimize my down time to the time it took me to setup this laptop.
