MANA relies on page_pool for RX buffers, and the buffer refill paths can behave quite differently across architectures and configurations (e.g. base page size, fragment vs full-page usage). This makes it harder to understand and compare RX buffer behavior when investigating performance and memory differences across platforms.Standard stats must not be duplicated in ethtool -S. ynl and ynltool provide easy access to these stats # ynltool page-pool stats eth0[2] page pools: 44 (zombies: 0) refs: 495680 bytes: 2030305280 (refs: 0 bytes: 0) recycling: 100.0% (alloc: 7745:2097593009 recycle: 379301630:1717888312)
Thanks Jakub for the feedback, and understood the generic page pool stats should be combined with ethtool -S. I will drop this patch and use ynltool page-pool stats. Regards
