_nx_ip_interface_status_check blocks undefinitely

[mapellil]

Describe the bug Calling the nx_ip_interface_status_check(,,, needed_status, timeout) with timeout>0 in case the needed_status condition is not meet the API block indefinitely. The same apply for nx_ip_status_check() API. The issue seems to come from the tx_mutex_get(&(ip_ptr -> nx_ip_protection), TX_WAIT_FOREVER); called within the above APIs.

To Reproduce eg. in case of wifi interface after having entered a wrong password the call to nx_ip_status_check(&IpInstance, NX_IP_INITIALIZE_DONE | NX_IP_LINK_ENABLED | NX_IP_INTERFACE_LINK_ENABLED, &actual_status, NX_IP_PERIODIC_RATE*5); will block undefinitely.

Expected behavior the nx_ip_status_check(), when called with timeout>0, should return if timeout expire

What platform did you use? One solution is to move WIFI connect from network driver to the application.

Thanks for the suggestion, however i do not expect to find a blocking call tx_mutex_get(&(ip_ptr -> nx_ip_protection), TX_WAIT_FOREVER) within a timed API nx_ip_status_check() because, if for any reason the API internal mutex is not released the API also become blocking regardless of the timer specified in the args.

In Azure RTOS, cost on the mutex waiting is not part of timeout. So it is not likely to change the logic here.
