-/* ATH9K_TXDESC_INTREQ forces a tx interrupt to be generated for

- * descriptors when the h/w hits an EOL condition or
- * when the descriptor is specifically marked to generate
- * an interrupt with this flag. Descriptors should be
- * marked periodically to insure timely replenishing of the
- * supply needed for sending frames. Defering interrupts
- * reduces system load and potentially allows more concurrent
- * work to be done but if done to aggressively can cause
- * senders to backup. When the hardware queue is left too
- * large rate control information may also be too out of
- * date. An Alternative for this is TX interrupt mitigation
