/**
This is the SNP interface routine for shutting down the interface
This routine basically retrieves snp structure, checks the SNP state and
calls the pxe_shutdown routine to actually do the undi shutdown
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.
@param this context pointer
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
@retval EFI_SUCCESS The network interface was shutdown.
@retval EFI_NOT_STARTED The network interface has not been started.
@retval EFI_INVALID_PARAMETER This parameter was NULL or did not point to a valid
EFI_SIMPLE_NETWORK_PROTOCOL structure.
@retval EFI_DEVICE_ERROR The command could not be sent to the network interface.
