From: Björn Töpel <bjorn.topel@xxxxxxxxx>
The test_xdp_redirect.sh script uses a bash feature, '&>'. On systems,
e.g. Debian, where '/bin/sh' is dash, this will not work as
expected. Use bash in the shebang to get the expected behavior.
Further, using 'set -e' means that the error of a command cannot be
captured without the command being executed with '&&' or '||'. Let us
use '||' to capture the return value of a failed command.
v3: Reintroduced /bin/bash, and kept 'set -e'. (Andrii)
v2: Kept /bin/sh and removed bashisms. (Randy)
