How to change i210 MAC address at boot time

Hello.

We are using own design E8300 board with integrated i210 and custom OS.

MAC address flashed to the NVRAM and loads by card after reset.

At this time I'm trying to change MAC address from driver.  After changing RAL0 or RAH0 registers board doesn't receiving packets. Also I'm trying write new address to another RAL0-15 and RAH0-15 registers with same result.

RCTL.UPE = 0 ( Unicast Promiscuous mode Disabled )

Is there any way to to temporary change MAC address and use it with MAC Address Filter?

Hello, @CarlosAM_INTEL.
Thank you for answer. I already read this FAQ. I don't want change data in the internal flash memory. Hardware registers RAL[n] and RAH[n] described as a RW access and I can write new address to this registers. Looks like need write new address also to another register for correct work L2 mac address filter.

Hello @CarlosAM_INTEL,

As I wrote above I can't use this tools, because we are using custom OS.

Page 435 of "PCIe* GbE Controllers Open Source Software Developer’s Manual" Revision 2.5 contains this info:

"The operating system provides a list of addresses that it would like to respond to. The driver fills in the Receive Address Registers (RAR) first, as these are exact matching addresses...".

In first post I'm already wrote that my driver write new address to RAR registers, but i210 don't provide packets with this address to  the OS.
