[ Upstream commit732fa32330] 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 restructure the ping-commands, and use them as an if-expression, so that we can capture the return value. v4: Added missing Fixes:, and removed local variables. (Andrii) v3: Reintroduced /bin/bash, and kept 'set -e'. (Andrii) v2: Kept /bin/sh and removed bashisms.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
