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.
