test_sockmap was originally written only to exercise kernel code paths, so there was no strict checking of errors. When the code was modified to run as selftests, due to lack of error handling it was not able to detect test failures.

In order to improve, this series fixes error handling, test run time and data verification.

Also slightly improved test output by printing parameter values (cork, apply, start, end) so that parameters for all tests are displayed.

Changes in v4: - patch1: Ignore RX timoute error only for corked tests - patch3: Setting different timeout for corked tests and reduce run time by reducing number of iterations in some tests

Changes in v3: - Skipped error checking for corked tests
