June 15: 
- Completed: skge_devinit()

- Meeting with Marty: I spoke on the phone with Marty today for about 90 minutes. We discussed my progress and he reviewed my code up until now. Overall, it was a very constructive meeting.\\
- Key recomendations of that conversation were:\\
 - ensure code formatting is consistant with the rest of the code base\\
 - ensure assumptions are not made (such as mac address length)\\
 - remove certain unnecessary functions that were implemented by linux, but unnecessary for gPXE\\

- shortly after the meeting, I committed and headed to bed.\\

June 16: \\
- Completed: skge_probe() !\\
- imported a few more constants that were defined in linux-2.6/drivers/net/skge.c that had to do with implementation of probe\\
- Screenshot (to be inserted) of gpxe recognizing my network card\\
- Reformatted some bits of code to comply with coding standards;\\
- %s/<8xspace>/<tab>/g\\
- Verified device recognition:\\

June 17:
GRRR. Power outage put me back about 20 minutes. Not horrible, but ... grrr. Now, a BSOD, i could have dealt with. Infact, I'm almost comfortable with blue screens. However, the power here... very rarely goes off. 


On a completely non-important note, tim hortans coffee and bagles are awsome. </advertisement>


- Inserted lines for doxygen compiling,\\
- built "make doc" several times \\
- changed "EXPORT_ALL" to yes in doxygen.cfg \\
- changed the directory in doxygen.cfg to generate to /var/www/pxe.asdlkf.net/doxy\\
- (output available at http://pxe.asdlkf.net/doxy/) \\

- rwcr reviewed (briefly) the code I have written, he seemed pleased; pointed out a few \\ 
variables that are set in other units that i can use instead of declairing them in skge.c

- spoke with rwcr about the datastructure and dma access of the rx and tx descriptors\\
- I believe I'm going to implement a circularly linked data structure resembling this:

<code>
struct tx_queue:
	|->tx_descriptor
	|->io_buffer 
	|->*tx_queue
</code>

I should be able to implement that quite easily; Ill get started on open tomorrow when I get home.


June 18: 11:25 PM: It seems unlikely Ill get much done today. Due to a mishap at work (read: customers AD needs to be restored), I will only be able to work for about an hour today. 

Lets see how far I can get by 12:30.
