CONFIG_ETH_MCUX_0_RANDOM_MAC

Random MAC address

Type: bool

Help

Generate a random MAC address dynamically on each reboot. Note that using this choice and rebooting a board may leave stale MAC address in peers’ ARP caches and lead to issues and delays in communication. (Use “ip neigh flush all” on Linux peers to clear ARP cache.)
