>@masayuki2009 Sorry, I'm not familiar with kernal mode, I see there is no
iperf command after starting the rv-virt:knetnsh64 (Follow the README.txt).
>Could you show me more detail steps to run the built-in command in kernal
mode.
@CV-Bowen
In the CONFIG_BUILD_KERNEL mode, iperf command is built as a separate ELF
file so the command can not be seen in the help.
