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.
