| + | Today I added the code to initialize tp->dma_rwctrl. For now I also disabled the code to allocate resources needed for packet reception, as we don't have any other code for receiving packets for now. | ||
| + | I tried to send some packets but failed. I noticed that gPXE didn't detect the correct link state and the other machine of the link negotiated to 10MBit/s half duplex while 1000MBit/s full duplex would be possible. | ||
| + | To debug the issue I moved all the PHY functions to a new file, tg3_phy.c. After some fixes the other machine was able to detect the link speed correctly, but gPXE still detected the link as down. | ||
