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.

The udpgro_fwd.sh self-tests are somewhat unstable. There are
a few timing constraints the we struggle to meet on very slow
environments.
Instead of skipping the whole tests in such envs, increase the
test resilience WRT very slow hosts: increase the inter-packets
timeouts, avoid resetting the counters every second and finally
disable reduce the background traffic noise.
Tested with:
for I in $(seq 1 100); do
./tools/testing/selftests/kselftest_install/run_kselftest.sh \
-t net:udpgro_fwd.sh || exit -1
done
in a slow environment.

After commit afef88e655 ("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.

udpgro_fwd.sh contains many bash specific operators ("[[", "local -r"),
but it's using /bin/sh; in some distro /bin/sh is mapped to /bin/dash,
that doesn't support such operators.
Force the test to use /bin/bash explicitly and prevent false positive
test failures.

Create a bunch of virtual topologies and verify that
NETIF_F_GRO_FRAGLIST or NETIF_F_GRO_UDP_FWD-enabled
devices aggregate the ingress packets as expected.
Additionally check that the aggregate packets are
segmented correctly when landing on a socket
Also test SKB_GSO_FRAGLIST and SKB_GSO_UDP_L4 aggregation
on top of UDP tunnel (vxlan)
v1 -> v2:
- hopefully clarify the commit message
- moved the overlay network ipv6 range into the 'documentation'
reserved range (Willem)
