#### 5.2.X.x Requirement
The network interface shall implement mechanisms to observe when the firmware and/or software of the network interface is no longer capable of performing its functions and automatically reset the network interface to a functioning state.
The network interface shall implement mechanisms to observe when the firmware and/or software of the network interface is no longer capable of performing its functions and automatically reset the network interface to a functioning state or notify another part of the system.
#### 5.2.X.x MI-WDOG: Watchdog to reset network interface
The network interface shall implement a watchdog mechanism that observes whether the network interface is capable of performing its functions. If the watchdog observes that the interfaces is not capable of performing its functions for a significant period of time, it will reset the network interface to a functioning state using a hardware-based mechanism.
* Applicabilty: only applies to physical network interfaces
* Test: use a testing interface to halt the firmware or sofware, wait for the watchdog to reset the firmware, and then attempt to use a network interface function after any necessary initialization or configuration
* Test: use a testing interface to halt the firmware or software, wait for the watchdog to reset the firmware, and then attempt to use a network interface function after any necessary initialization or configuration
* Result: after a specific time period has elapsed, the interface restarts, any initialization or configuration succeeds, and the use of the network interface function succeeded
* Output: error, log message, statistics update, or other information from card indicating reset has occurred, log message or statistic showing the post-reset test function succeeded
* False positive prevention: do not use any network interface functions for N+1 seconds and see that it does not reset
#### 5.2.X.x MI-NTFY: Notify fatal errors to ask for reset and/or firmware reload
The network interface shall implement a notification mechanism to inform the host whether the network interface is not capable of performing its functions.
* Test: use a testing interface to inject errors and verify the related notification to host
* Result: after a specific fault the related notification is received by the host
* Output: error, log message, statistics update, or other information from card indicating error notification
