SnpUndi32Shutdown()

EFI_STATUS EFIAPI SnpUndi32Shutdown

(

IN EFI_SIMPLE_NETWORK_PROTOCOL *

This

)

Resets a network adapter and leaves it in a state that is safe for another driver to initialize.

This function releases the memory buffers assigned in the Initialize() call. Pending transmits and receives are lost, and interrupts are cleared and disabled. After this call, only the Initialize() and Stop() calls may be used. If the network interface was successfully shutdown, then EFI_SUCCESS will be returned. If the driver has not been initialized, EFI_DEVICE_ERROR will be returned.

Parameters

This	A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.

Return values

EFI_SUCCESS	The network interface was shutdown.
EFI_NOT_STARTED	The network interface has not been started.
EFI_INVALID_PARAMETER	This parameter was NULL or did not point to a valid EFI_SIMPLE_NETWORK_PROTOCOL structure.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
