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.

Hangbin Liu (4):
selftests/bpf/xdp_redirect_multi: put the logs to tmp folder
selftests/bpf/xdp_redirect_multi: use arping to accurate the arp
number
selftests/bpf/xdp_redirect_multi: give tcpdump a chance to terminate
cleanly
selftests/bpf/xdp_redirect_multi: limit the tests in netns
