RXDCTL.ENABLE register could not set on I210 Card

[anilkaradag]

Hi,

I use a custom network driver for Intel I210 card. Card initialization is different than general purpose drivers(i.e. igb) due to we need to faster. The card can be initialized and used by OS in legacy BIOS; but RXDCTL/TXDCTL bits could not be enabled on UEFI BIOS.

p.s.: when network stack is enabled in UEFI BIOS; the mentioned bits are set properly by the custom driver.

Does anyone know that why?

Hello anilkaradag,

Thank you for posting in Intel Ethernet Communities.

Can you share where did you get the custom network driver for Intel I210 card? Are you designing/programming your own driver for the I210? Is the I210 a discrete LAN card or is it embedded on the motherboard?

We look forward to your response.

In case we don’t hear from you, we’ll follow up after 3 business days.

Hi,

We use onboard card; yeap the using driver has been developed by design team in the long time ago. I found a patch for e1000 driver for giving support of I210 card. Why rxdct/rtxdct bits writing request rejected? which operation is mandatory before that?
