second ethernet MAC

[jugge]

I can hardcode it through u_boot_env, but was hoping on copying how the MAC is set for eth0 and doing it in our custom build of TorizonCore.
Could you direct me to where it is done in the Yocto build?

Also, I forgot to mention in the question that if there is a way to use a Toradex MAC for eth1 that would be our first choice, but as I understand from other posts there is not?

Second eth MAC address not assigned on I.MX8X

We do not need the second eth in Uboot so we can assign it during Linux startup, but does the module come from toradex with a second MAC assigned in production or do we need to define the second MAC from our range? Is the MAC programmed by toradex stored in eMMC, eeprom, or OTP bits?

For other modules I think I read that the second ethernet got the same MAC as eth0, but offset 0x100000 or something?
