Subject: [PATCH net-next v3] selftests: net: vrf_strict_mode_test: add
 support to select a test to run

Add a boilerplate test loop to run all tests in
vrf_strict_mode_test.sh. Add a -t flag that allows a selected test to
run.

Signed-off-by: Jaehee Park <jhpark1013@...il.com>

version 3:
- Added commented delineators to section the code for improved 
readability.
- Moved the log_section() call into the functions handling the tests.
- Removed unnecessary spaces.
