/* ATH9K_TXDESC_INTREQ forces a tx interrupt to be generated for
 * the descriptor its marked on.  We take a tx interrupt to reap
 * 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
 * but this needs more testing. */
