The driver supports 2 methods to define 3 last bytes of MAC address
1. Statically defined by user
2. Generated dynamically at each boot
Note: Configuring this methods using Kconfig is now deprecated in favor
of device tree based configuration.

performances.
See reference manual for more information on this feature.

a dependency from the network stack that this device
initializes before network stack (NET_INIT_PRIO).

config ETH_STM32_MULTICAST_FILTER
bool "Multicast hash filter support"
help
Enable support for multicast hash filtering in the MAC.
Once enabled the ethernet MAC performs imperfect filtering
based on a computed hash of the destination MAC address of
the multicast address. Only multicast with the computed
hash set in the multicast table will be received and all
other multicast is dropped by the MAC. If disabled then all
multicast is received by the MAC.
