[Devel] [PATCH vz10 4/4] selftests: net: skip test_bpf if kernel module is unavailable

[Konstantin Khorenko]

Same here:

So you state that those modules were not loaded automatically and the test must preload them.
At the same time those modules are loaded automatically in VHP env.

So what is the difference? Why in HCI 7.3 modules were not loaded automatically?
We definitely need to understand this because that might cause issues with other userspace in case 
modules are not being loaded automatically due to some reason.

+ why it's correct to skip the test in case the module fails to be loaded?
