====== Day 1 ( Aug 8 ) ======

I did some cleanups in the code today. I also implemented tg3_close() and tg3_remove_one(). Those were the last two missing functions and implementing them resulted in a successful first boot of the driver :).

====== Day 2 ( Aug 9 ) ======

More cleanups. Removed most of the out-commented code that was left in the driver and some other simplifications. While going through the code I also compiled a list of suspicious looking things that I want to revisit the coming days.

====== Day 3 ( Aug 10 ) ======

Not much coding today, but a lot of testing. Tested the driver with all 4 test cards I have available, testing:
  * Booting linux + initrd over HTTP and TFTP
  * Booting linux over iSCSI
  * Booting MSDOS over iSCSI, running scandisk on a 512MB iSCSI disk.

Interrupt support is not fully implemented yet, so UNDI chainloading tests were saved for later. Will see if I can get ahold of a Symantec Ghost DOS disk to stresstest the UNDI/interrupt support.

I was doing all that testing in Vienna and unfortunately forgot one test card there, so I only have 3 cards to test until the next time I get to Vienna(Probably next week).

====== Day 4 ( Aug 11 ) ======

I moved kicking off autoneg to tg3_init_one() from tg3_open(). This results in the BANNER_TIMEOUT being used for auto negotiation, which should save a few seconds boot time, as autoneg can take up to 6 seconds to complete.
struct tg3_napi was also removed and its fields merged into struct tg3.

====== Day 5 ( Aug 12 ) ======

Moved programming of the MAC address to tg3_open() instead of tg3_init_one(), as dictated by the gPXE API specifications.
Also removed was the NIC stats block, which saves some heap memory.
I also removed more leftover code.

====== Day 7 ( Aug 14 ) ======

A little interrupt related work. Completely untested and I still have to clear up some uncertainty on my side about tagged irq status, especially tp->last_tag.
