 Pushed the tg3_transmit() code to iret. Today I tested the open and transmit code. My test machine locks up or reboots after open() is called(sometimes),​ and I was trying to find the cause of this bug. I'm probably messing up some pointer and/or DMA addresses, but haven'​t found out which one yet. Pushed the tg3_transmit() code to iret. Today I tested the open and transmit code.

 +====== Day 4 ( June 23 ) ======
 +
 +I continued debugging the crash/​reboot issue today. Unfortunately I don't have any equipment for a serial console in my apartment in Vienna, and I can't make out the text before the machine reboots on any of my test machines. I have to insert code to deliberately freeze/hang the machine after every line of debugging output and test gPXE, which makes this a slow and tedious task. Unfortunately I haven'​t found the bug so far.

 +====== Day 5 ( June 24 ) ======
 +
 +After an exam today I finally got home where I could test gPXE with a serial console. This made debugging a lot easier, and I located the bug to be an uninitialized field in the private driver structure( tp->​dma_rwctrl). I started porting the function to initialize this field. Hopefully we won't discover much more bugs.
