Guo-Fu Tseng: Implement and Port Ethernet Drivers for gPXE

In order to obtain better performance from JMicron Ethernet Card. Instead of using the UNDI driver, I would implement a better performance native driver for gPXE. The tg3 driver of gPXE project still using old etherboot API, I would buy a Broadcom NIC and try to port it into new gPXE API.

• Week 1-2:
  
  • Trace the underlining implementation of gPXE for drivers, try to get the picture how would the gPXE acted while calling them. So that I can design and control the driver's flow in the next weeks.
• Week 3-4:
  
  • Implement the basic transmit and receive function in polling mode. To make sure that all the PCI and DMA actions are performed correctly.
• Week 5-6:
  
  • Link change event recover, review code, heavy load testing, debugging.
• Week 7:
  
  • Trace tg3 driver of both Linux and gPXE.
• Week 8-10:
  
  • Convert tg3 driver from old etherboot API to new gPXE API.
• Week 11-12:
  
  • Testing and Debuging.

• Ethernet RX checksum offloading support
• TCP out-of-order receive queue
• TCP Selective acknowledgement [RFC 2018][RFC 1323]
• TCP Window scale [RFC 1323]
• TCP PAWS(Protect Against Wrapped Sequence Nunbers) [RFC 1323]
• Possible tunning TCP/HTTP xfer interface.
