Hi! This small series allows test_offload.py selftest to run on modern distributions which may create BPF programs for cgroups at boot, like Ubuntu 18.04. We still expect the program list to not be altered by any other agent while the test is running, but no longer depend on there being no BPF programs at all at the start.
Fixing the test revealed a small problem with bpftool, which doesn't report the program load time very accurately. Because nanoseconds were not taken into account reported load time would fluctuate by 1 second. First patch of the series takes care of fixing that.
