Getting IP after some delay (because of monitor_work_handler) on nucleo_h743zi board When using ethernet and zephyr 3.7.1

Issue: Getting Ip after some delay because of phy_mii_initialize() , MII PHY auto-negotiate sequence and monitor_work_handler()

• Using On zephyr 3.7.1 with eth_stm32_hal.c

• In file phy_mii.c under invoke_link_cb() the callback is coming as NULL, so no callback is called from invoke_link_cb. It seems eth_stm32_hal.c doesnt sets any callback, but monitor_work_handler() runs continuously with frequency of CONFIG_PHY_MONITOR_PERIOD (500ms) **Q1: what is its use in this case? **

• Ethernet connect/disconnect is handeled in eth_stm32_hal.c in rx_thread() using net_eth_carrier_on() and net_eth_carrier_off(), Q2: In this case what is the use of phy_mii_initialize and monitor_work_handler() which is running contuinuoulsy ?

• If I want to disable the below configs then not able to do because of the dependency present in eth_stm32_hal.c.
  CONFIG_PHY_GENERIC_MII=n
  CONFIG_ETH_STM32_AUTO_NEGOTIATION_ENABLE=n

• If I am commenting the content of monitor_work_handler() getting IP in expected time.

In this case what should I do, If I don't want to upgrade my zephyr 3.7.1 version, but OK to use any patch if required.
