From 93188e9642c3ce11d11b2663905b703dfe89e349 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Fri, 6 Aug 2021 10:46:22 +0800 Subject: net: hns3: support skb's frag page recycling based on page pool This patch adds skb's frag page recycling support based on the frag page support in page pool. The performance improves above 10~20% for single thread iperf TCP flow with IOMMU disabled when iperf server and irq/NAPI have a different CPU. The performance improves about 135%(14Gbit to 33Gbit) for single thread iperf TCP flow when IOMMU is in strict mode and iperf server shares the same cpu with irq/NAPI.
