Jiri reported some issues in test_xdp_redirect_multi.sh. Like the test logs not cleaned after testing. The tcpdump not terminated cleanly. arp number count may have false positive. And the most important, after creating/deleting a lot interfaces, the interface index may exceed the DEVMAP max entry and cause program xdp_redirect_multi exec failed.
This patch set fix all these issues.
