[][kernel-6.6][common][eth][Add Ethernet HW LRO support] [Description] Add Ethernet HW LRO support. We can use the standard interface command to adjust the HW LRO configuration. Add HW LRO RX rule: ethtool -N [interface] flow-type tcp4 dst-ip [IP] action 0 loc [0/1] Delete HW LRO RX rule: ethtool -N [interface] delete [0/1] Enable/Disable HW LRO rule: ethtool -K [interface] lro [on | off] Show the current offload features: ethtool -k [interface] We can use the following command to adjust SMP affinity, ensuring that interrupts are evenly assigned to 4 CPUs: echo [CPU bitmap num] > /proc/irq/[virtual IRQ ID]/smp_affinity. Since HW LRO only has 4 RX rings, we can only accelerate 4 streams simultaneously. We were able to measure RX throughput of 9.4Gbps using iperf3 on the MT7988A. The experimental command is as follows, PC: iperf3 -c [IP] -P 4 DUT: iperf3 -s When we added the HW LRO feature, we also adjusted the global configuration of ADMA and the usage conditions of the page pool, increasing the RX throughput of RSS from 7.3Gbps to 9Gbps.
