Hi,
Regarding "invalid" Ethernet address.
Is there a reliable way to set the default environment that will prevent
Ethernet communications from being attempted.
That is, when an Ethernet capable system is brand new and before an
Ethernet MAC address has been assigned to that system during
manufacturing with the "setenv ethaddr" command, how can Ethernet comms
be disabled?
This would be a fail-safe to make sure that part of the manufacturing
process is done correctly and that an Ethernet address is intentionally
assigned.
Thanks,
Jim

Use random ethernet address if the ethernet address found
is invalid, not zero and config for random address
is defined.
