Incorrect NAPI polling caused WARNING at net/core/dev.c net_rx_action. Some stability issues were also seen at high throughput and system load before this patch. This patch contains several changes in altera_tse_main.c: - tse_rx() is fixed to not process more than `limit` frames - tse_poll() is refactored to match NAPI logic - only received frames are counted for return value - removed bogus condition `(rxcomplete >= budget || txcomplete > 0)` - replace by: if (rxcomplete < budget) -> call __napi_complete and enable irq - altera_isr() - replace spin_lock_irqsave() by spin_lock() - we are in isr - use spinlocks just over irq manipulation, not over __napi_schedule - reset IRQ first, then disable and schedule napi This is a cleaned up resubmission from Vlastimil's recent submission.
