Function Documentation

EFI_STATUS EFIAPI VirtioNetGetStatus	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		OUT UINT32 *InterruptStatus	OPTIONAL,
		OUT VOID **TxBuf	OPTIONAL
	)

Reads the current interrupt status and recycled transmit buffer status from a network interface.

Parameters

This	The protocol instance pointer.
InterruptStatus	A pointer to the bit mask of the currently active interrupts If this is NULL, the interrupt status will not be read from the device. If this is not NULL, the interrupt status will be read from the device. When the interrupt status is read, it will also be cleared. Clearing the transmit interrupt does not empty the recycled transmit buffer array.
TxBuf	Recycled transmit buffer address. The network interface will not transmit if its internal recycled transmit buffer array is full. Reading the transmit buffer does not clear the transmit interrupt. If this is NULL, then the transmit buffer status will not be read. If there are no transmit buffers to recycle and TxBuf is not NULL, * TxBuf will be set to NULL.

Return values

EFI_SUCCESS	The status of the network interface was retrieved.
EFI_NOT_STARTED	The network interface has not been started.
EFI_INVALID_PARAMETER	One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	This function is not supported by the network interface.
