Dynamic mac on Raspberry Pi network port after reboot. How to fix?

Question

linux

does not cause inconvenience. as I see a new lease on the monitoring. but already kalit. what is the reason and how to fix it?

Answer 1

In the interface config, write:
MACADDR=<any:needed:mac:address>
NM_CONTROLLED=no
Then the poppy will be set statically based on the config, and not from the bullshit.
There are such glitches with some setevukha. There is a driver bug, there is a jamb of the adapter itself. Look in dmesg for the lines:
Invalid Mac address detected:
Please complain to your hardware vendor. Switching to a random MAC.
