How to change Inter Frame Gap(Inter Packet Gap) of I350 controller

[MHLee]

Hello, 

I'm trying to change from default 8 bytes IFG value to 12 bytes.

Anyone who give me a way to change this value ?

I found that it is not possible to change IFG through Windows Driver setting thruogh googling.

It seems like to change IFG through lanconf utillty but lanconf utility can change IFG only temperary.

I think Transmit IPG Register - TIPG (0x0410; R/W) must be set via EEPROM but I can't find the TIPG offset on EEPROM map.  

Thank you.

I350 datasheet > go to Topic 8.12.3 > under Transmit IPG Register - TIPG (0x0410; R/W) page 534

You can identify the changes of initial values for the Inter Packet Gap.

Thank you for your reply.

I have already read this information on I350 datasheet and I’d like to know how to set the value that I want to power on default value.

I have changed the value I want through “lanconfw64e.exe” but it was temporary.

I think it must be implemented some kind of changing EEPROM image.

Best regards,
