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