[][kernel-6.6][common][eth][Add Ethernet RSS support] [Description] Add Ethernet RSS support. We can adjust SMP affinity with the following command: echo [CPU bitmap num] > /proc/irq/[virtual IRQ ID]/smp_affinity, with interrupts evenly assigned to 4 CPUs, we were able to measure an RX throughput of 7.3Gbps using iperf3 on the MT7988. Further optimizations will be carried out in the future. The experimental command is as follows, PC: iperf3 -c [IP] -P 10 DUT: iperf3 -s The entire indirection table can be imagined as 128 buckets, we can use the ethtool command to mark which RX ring we want to send the packets in these buckets to. Show RSS RX ring parameters in indirection table and RSS hash key: ethtool -x [interface] Change RSS RX rings weight under uniform distribution: ethtool --set-rxfh-indir [interface] equal [ring num] Change RSS RX rings weight under non-uniform distribution: ethtool --set-rxfh-indir [interface] weight [ring0 weight] [ring1 weight] [ring2 weight] [ring3 weight] [Release-log] N/A Change-Id: I3f39300545dbf9ffe912cde7fc9761361fe0a728 Reviewed-on: https://gerrit.mediatek.inc/c/openwrt/feeds/mtk_openwrt_feeds/+/10130517
