 I removed the jumbo frame support from the driver today. Support for ethtool stats and rx copy threshold was removed too. The changes were tested on 2 different testing cards by moving around a 1.5gb file over the network. The modified driver was used alternatively on the sending and the receiving end and no issues were observed. I removed the jumbo frame support from the driver today.

 +====== Day 3 ( June 1 ) ======

 +Unfortunately no progress was made today. I had to meet a deadline for college and worked on college things first. When I was getting started with driver stuff I got a somewhat unexpected visit from some friends.
 +I will try to make up for the lost time on the weekend as I hope to be not so busy then.

 +====== Day 4 ( June 2 ) ======
 +
 +MSI/MSIX support was the victim of today. This simplifies the interrupt setup and handling code. None of the benefits of MSI/MSIX are relevant in gPXE.
 +I tested this commit on all 4 card variants and also used a more thorough test to expose any bugs that might have been introduced in this or any previous commit. I couldn'​t find any issues which is starting to make me suspicious :P.
 +With the (unpushed) removal of the firmware loading support we have removed over 3500 LoC so far. Hopefully many more will follow soon :)
 +
 +====== Day 5 ( June 3 ) ======
 +
 +Today I started importing the driver code into the gPXE tree. I copied and adapted the tg3_init_one() function for gPXE and started doing the same for tg3_get_invariants().
 +It doesn'​t build yet, so I hadn't commited it to git before. I commited it for the weekly meeting and pushed it to my repository now.
