i wonder why you have with rss alone only 4.5 GBit/s…do you do bidir iperf-check? i had around 7.2GBit/s with RSS, but there was an iperf3 issue too where i had to use iperf2…not sure if it was RSS or LRO
btw. RSS/LRO is currently reworked by mtk due to the report from user mescheen (LRO does only catch a small amount of packets)
i’m not sure the corruption is caused by LRO or the mainline-code…but yes, there are patches for it from mescheen in my latest branches
