config BR2_PACKAGE_IPERF3 bool "iperf3" depends on BR2_TOOLCHAIN_HAS_THREADS help iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters. It's a redesign of the NLANR/DAST iperf(2) and is not backward compatible. https://github.com/esnet/iperf comment "iperf3 needs a toolchain w/ threads" depends on !BR2_TOOLCHAIN_HAS_THREADS
