Does anyone have an ethernet card with an intel i210 or i211 controller on hand that they could read something from (specifically the iNVM)? This requires root access on linux. I want to compare if maybe the iNVM configuration is keeping this chip from starting up properly, and since it's OTP, I only have a limited amount of tries to change things. There's probably something in the UEFI that handles whatever additional setup is needed, but I haven't found that part yet unfortunately.

    To read out the iNVM, read 64 32-bit words starting at 0x12120 from BAR 0 of the controller (with something like pcimem). This does (or at least should) contain your MAC address, if you want to keep that private.
