====================
This patch series continues the work to migrate the *.sh tests into
prog_tests framework.
test_xdp_redirect_multi.sh tests the XDP redirections done through
bpf_redirect_map().
This is already partly covered by test_xdp_veth.c that already tests
map redirections at XDP level. What isn't covered yet by test_xdp_veth is
the use of the broadcast flags (BPF_F_BROADCAST or BPF_F_EXCLUDE_INGRESS)
and XDP egress programs.
Hence, this patch series add test cases to test_xdp_veth.c to get rid of
the test_xdp_redirect_multi.sh:
- PATCH 1 & 2 Rework test_xdp_veth.c to avoid using the root namespace
- PATCH 3 and 4 cover the broadcast flags
- PATCH 5 covers the XDP egress programs
NOTE: While working on this iteration I ran into a memory leak in
net/core/rtnetlink.c that leads to oom-kill when running ./test_progs in
a loop. This leak has been fixed by commit 1438f5d07b ("rtnetlink:
fix netns leak with rtnl_setlink()") in the net tree.

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.
