Several net tests requires an XDP program build under the ebpf
directory, and error out if such program is not available.
That makes running successful net test hard, let's duplicate into the
net dir the [very small] program, re-using the existing rules to build
it, and finally dropping the bogus dependency.

The sockets used by udpgso_bench_tx aren't always ready when
udpgso_bench_tx transmits packets. This issue is more prevalent in -rt
kernels, but can occur in both. Replace the hacky sleep calls with a
function that checks whether the ports in the namespace are ready for
use.

After commit afef88e65554 ("selftests/bpf: Store BPF object files with
.bpf.o extension"), we should use xdp_dummy.bpf.o instade of xdp_dummy.o.
In addition, use the BPF_FILE variable to save the BPF object file name,
which can be better identified and modified.

In some conditions, background processes in udpgro don't have enough
time to set up the sockets. When foreground processes start, this
results in the test failing with "./udpgso_bench_tx: sendmsg: Connection
refused". For instance, this happens from time to time on a Qualcomm
SA8540P SoC running CentOS Stream 9.
To fix this, increase the time given to background processes to
complete the startup before foreground processes start.

Since commit 8fffa0e3451a ("selftests/bpf: Normalize XDP section names in
selftests") the xdp_dummy.o's section name has changed to xdp. But some
tests are still using "section xdp_dummy", which make the tests failed.
Fix them by updating to the new section name.

The udpgro.sh will always return 0 (unless the bpf selftest was not
build first) even if there are some failed sub test-cases.
Therefore the kselftest framework will report this case is OK.
Check and return the exit status of each test to make it easier to
spot real failures.

The current implementation for UDP GRO tests is racy: the receiver
may flush the RX queue while the sending is still transmitting and
incorrectly report RX errors, with a wrong number of packet received.
Add explicit timeouts to the receiver for both connection activation
(first packet received for UDP) and reception completion, so that
in the above critical scenario the receiver will wait for the
transfer completion.

Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.
rfc v3 -> v1:
- use ip route to attach the xdp helper to the veth
rfc v2 -> rfc v3:
- add missing test program options documentation
- fix sporatic test failures (receiver faster than sender)
