Hi, I have E810-C 2x100G NIC, the perf tool shows scalar rx path and not vectorized rx path. When I turn off Rx Offload (NIC rx timestamp) I see vectorized rx path in perf tool. Why is this a drawback and is this with just the E810 NIC?
See the comment on line [1]. By the sound of it, this is somewhat expected. [1] https://github.com/DPDK/dpdk/blob/fa3aca8a525decfd12bd5fa01ebc98789d5f7278/drivers/net/intel/common/rx.h#L104 Thank you.
is there a way around this so Rx Offload Rx Timestamp can be used in our application and get vectorized rx path? We need rx timestamps of packets and max performance. Thanks, Ed
