Currently, we only check the latest senders's exit code. If the receiver
report failed, it is not recoreded. Fix it by checking the exit code
of all the involved processes.
Before:
bad GRO lookup ok
multiple GRO socks ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
failed
$ echo $?
0
After:
bad GRO lookup ok
multiple GRO socks ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
failed
$ echo $?

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 reStructuredText 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.
