[Devel] [PATCH vz10 06/12] selftests: net: change port range to avoid bind conflicts

[Aleksei Oladko]

Some net kselftests use a fixed port range which overlap with process-exporter
service already running on the host. When such a conflict happens,
the test fail with:

  failed to bind receive socket: Address already in use

Update the port range used by the affected tests to avoid conflicts
with running daemon.
