RtndEnableTxInterrupt

RtndEnableTxInterrupt enables or disables the transmit interrupt for a specific Transmit Queue.

Syntax

BOOL RtndEnableTxInterrupt(
  [in]    ULONG_PTR RtndInterfaceId,
  [in]    ULONG TxQueueIndex,
  [in]    BOOL Enable
);

Parameters

[in] RtndInterfaceId

The number or pointer used to identify the interface. This value is returned by RtndManageInterface.

[in] TxQueueIndex

The index of the Transmit Queue.

[in] Enable

TRUE to enable the transmit interrupt, FALSE to disable it.

Return Value

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. To get extended error information, call GetLastError.

Common error codes:

Note: Custom drivers may return other error codes not listed above.

Remarks

The NL2 always calls this function from the NL2 process but not necessarily from the main thread.

If the NIC doesn’t have a per-queue transmit interrupt, the driver must enable the global transmit interrupt only when at least one of the Transmit Queues has been requested to enable its transmit interrupt.
