Reads the current interrupt status and recycled transmit buffer status from a

network interface.
|

|

This function gets the current interrupt and recycled transmit buffer status
|
||||
from the network interface. The interrupt status is returned as a bit mask in
|
||||
InterruptStatus. If InterruptStatus is NULL, the interrupt status will not be
|
||||
read. If TxBuf is not NULL, a recycled transmit buffer address will be retrieved.
|
||||
If a recycled transmit buffer address is returned in TxBuf, then the buffer has
|
||||
been successfully transmitted, and the status for that buffer is cleared. If
|
||||
the status of the network interface is successfully collected, EFI_SUCCESS
|
||||
will be returned. If the driver has not been initialized, EFI_DEVICE_ERROR will
|
||||
be returned.

@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.

@param InterruptStatus A pointer to the bit mask of the currently active

|
||||
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.
