Reads the current interrupt status and recycled transmit buffer status from
a network interface.
@param This The protocol instance pointer.
@param 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.
@param 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.
@retval EFI_SUCCESS The status of the network interface was retrieved.
@retval EFI_NOT_STARTED The network interface has not been started.
@retval EFI_INVALID_PARAMETER One or more of the parameters has an unsupported value.
@retval EFI_DEVICE_ERROR The command could not be sent to the network interface.
@retval EFI_UNSUPPORTED This function is not supported by the network interface.
