Tri-mode or gigebit ethernet support problem in ML403

[Ming Liu]

Dear Grant,
First, thanks for your help on my problem. 

So you mean, because there is no specific driver for TEMAC included in all 
versions of linux, I must port the driver from the BSP generated by EDK 
into the linux kernel by myself, right? I am sorry that I am a novice in 
linux field and I cannot understand you very well. Could you please give me 
more guidance on what shall I do to port the driver, in detail? Do you have 
some reference documents for me to do this? 

I really appreciate a lot for your kindly help on my work. Thank you so 
much.

Regards
Ming
