armv7 main [so: 14] targeting via poudriere bulk builds: iperf3 fails to build: iperf_api.c:4460:5: error: unknown type name 'cpu_set_t'; did you mean 'cpuset_t'?

Notably amd64 targeting did not have this problem. I've not
tried aarch64 targeting yet.

Still, it looks like iperf3 needs the #define _WITH_CPU_SET_T
opt-in someplace:
