Tested on x86 PC with EVB-LAN7430. The iperf3.7 TCPIP improved from 881 Mbps to 922 Mbps, and UDP improvedfrom 817 Mbps to 936 Mbps.quoted
Fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver") Signed-off-by: Yuiko Oshino <redacted>You seem to be posting performance optimizations as fixes. 800Mbps is not "broken" for a 1G interface. Please remove the Fixes tag and re- post this with [PATCH net-next]. Thank you!
Hi Jakub, no problem. Thank you for your comment. Yuiko
