Re: [PATCH 06/13] net: mvneta: enable mixed egress processing using HR timer

Hi Simon, I checked using hrtimer_is_queued instead of a custom flag and it resulted in ~20kpps drop in my setup. timer_scheduled flag is cleared in the tasklet, so no timer can be scheduled until the tasklet is executed. hr_timer flags do not cover this situation, so much more timers are

[PATCH 06/13] net: mvneta: enable mixed egress processing using HR timer

Mixed approach allows using higher interrupt threshold (increased back to 15 packets), useful in high throughput. In case of small amount of data or very short TX queues HR timer ensures releasing buffers with small latency. Along with existing tx_done processing by coalescing interrupts this
