> Whenever MGMT requests MAC addr change and FW does it, driver does not get aligned to that change. Current - legacy approach doesn't handle such scenario.

> Poll RAR0 (Receive Address Register) each service task cycle and update driver and netdev structs once new MAC addr is detected. It may happen that FW updates MAC address stored in RAR0 during runtime so SW shall fetch the new address.

> Refresh addr also during reset path to ensure the address survives RAR0 clearing during init_hw().
