Ira Snyder found that commit 8c7396ae "gianfar: Merge Tx and Rx interrupt for scheduling clean up ring" can cause hangs. It's because there was removed clearing of interrupts in gfar_schedule_cleanup() (which is called by an interrupt handler) in case when netif scheduling has been disabled. This patch brings back this action and a comment. Reported-by:
