ba5a6476e3 selftests: net: veth: test the ability to independently manipulate GRO and XDP
We should be able to independently flip either XDP or GRO states and toggling
one should not affect the other.

Adjust other tests as well that had implicit expectation that GRO would be
automatically enabled.

98cb12eb52 selftests: net: remove dependency on ebpf tests
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.

302e57f809 selftests/net: fix missing xdp_dummy
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.

d28b25a62a selftests/net: fix section name when using xdp_dummy.o
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.

0fd158b89b selftests: net: veth: make test compatible with dash
veth.sh is a shell script that uses /bin/sh; some distro (Ubuntu for
example) use dash as /bin/sh and in this case the test reports the
following error:

 # ./veth.sh: 21: local: -r: bad variable name
 # ./veth.sh: 21: local: -r: bad variable name

This happens because dash doesn't support the option "-r" with local.

Moreover, in case of missing bpf object, the script is exiting -1, that
is an illegal number for dash:

 exit: Illegal number: -1

Change the script to be compatible both with bash and dash and prevent
the errors above.
