====== Abstract ======
The aim of this project is to completely rewrite two legacy etherboot drivers present in iPXE: for VIA Rhine (VT6105M) and VIA Velocity (VT6122/VT6130) chipsets.

====== Deliverables ====== 
^ Deliverable ^ Week ^ Current status ^
| Investigate iPXE drivers API and PCI API    | 1  | **done** |
| Write skeleton for new VIA Rhine driver: probe and attach card, read EEPROM, communicate with MII PHY | 2, 3 | **done** |
| Write send and receive (polling) support for VIA Rhine | 4, 5 | **done** |
| Do functional and performance tests on driver | 6 | **done** |
| Write skeleton for VIA Velocity driver: probe, attach, read EEPROM and PHY | 7, 8 | **done** |
| Write send and receive support for VIA Velocity | 9, 10 | in progress |
| Do functional and performance tests on driver | 11 | in progress |
| Review the code and do final cleanup | 12 | not done |
| Commit code and write documentation | 13 | not done |

====== Daily progress =====
  - **2012.05.20**: Write skeleton for VIA Rhine driver based on skeleton.[ch]. Chip reset, MII read/write and reading MAC address from chip is working.
  - **2012.05.22**: Code style cleanup, introduce rhine_reload_eeprom() function to reload EEPROM contents. Working on link status notifications.
  - **2012.05.24**: **First packets are successfully sent using new Rhine driver!**
  - **2012.05.30**: **RX and TX now working - first successfull boot using new Rhine driver**
  - **2012.06.10**: Code cleanup, working on link status changes notifications
  - **2012.06.20**: **Rhine driver almost finished. Begun working on Velocity driver**
  - **2012.06.29**: Skeleton for VIA Velocity driver done
  - **2012.07.07**: VIA Velocity initialization, reset, EEPROM read, MII access and link status reporting works.
  - **2012.07.10**: Working on to get first packet transmitted and received on VIA Velocity
  - **2012.07.25**: TX and RX working with some minor issues
  - **2012.08.13**: Interrupt support (for UNDI) is working for both chips.

====== Test plan ======
  - Functional tests: transferring images, link state and speed changes
  - Performance tests: transfer speed
