**TxBuf
A pointer to the
EFI_SIMPLE_NETWORK
A pointer to the bit mask of the currently active interrupts (see
"Related Definitions"). 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.
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
NULL, * will be set to NULL.
