[Devel] [PATCH vz10 v2 2/5] selftests: net: skip test_blackhole_dev if kernel module is unavailable

[Aleksei Oladko]

The test_blackhole_dev.sh kselftest relies on the test_blackhole_dev
kernel module to be present and loadable. If the module in not built
or not available on the system, modprobe fails and the test is
reported as a failure.

Add an explicit check for the availability of the test_blackhole_dev
module and skip the test when the module is missing.
