I am using a Mellanox ConnectX-5 EN 100G NIC (driver mlx5_core 5.0-220.127.116.11, firmware 16.28.4000 (MT_0000000012)). However, I find many (seems) preset flow steering rules in the NIC (I am using mlx_fs_dump tool to dump fs rules). Is there any way to remove these flow steering rules? I also attached my dumped rules.
I want to remove these fs rules because I suspect these rules cause my NIC to perform much worst than other NICs I used before (which do not have any preset fs rules). And I indeed observed around 5x message rate drop compared to a ConnectX-5 EX 100G NIC without preset fs rules (although EX is more powerful than EN, I do not believe this would lead to 5x gap).
Any suggestions or comments are appreciated!
