* 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. */
