/* Wait for pending work items to complete. Since interrupts are
* disabled no new work will be scheduled.
Since the NAPI interrupts are basically ignored when NAPI is disabled we don't need to mask them within the functions bcmgenet_disable_tx_napi() and bcmgenet_disable_rx_napi(). So wait until all NAPI instances are disabled and mask all of the bcmgenet driver interrupts together in bcmgenet_netif_stop(). The interrupts can still be enabled in the functions bcmgenet_enable_tx_napi() and bcmgenet_enable_rx_napi(), but use the ring context int_enable() method to keep the functionality consistent and the code cleaner.
