187 * marked periodically to insure timely replenishing of the
188 * supply needed for sending frames. Defering interrupts
189 * reduces system load and potentially allows more concurrent
190 * work to be done but if done to aggressively can cause
191 * senders to backup. When the hardware queue is left too
192 * large rate control information may also be too out of
193 * date. An Alternative for this is TX interrupt mitigation
194 * but this needs more testing. */
