selftests: net: Remove executable bits from library scripts

[ Upstream commit 9d851dd4dab63e95c1911a2fa847796d1ec5d58d ]

setup_loopback.sh and net_helper.sh are meant to be sourced from other
scripts, not executed directly. Therefore, remove the executable bits from
those files' permissions.

This change is similar to commit 49078c1b80b6 ("selftests: forwarding:
Remove executable bits from lib.sh")

Fixes: 7d1575014a63 ("selftests/net: GRO coalesce test")
Fixes: 3bdd9fd29cb0 ("selftests/net: synchronize udpgro tests' tx and rx connection")

selftests/net: allow GRO coalesce test on veth

This change extends the existing GRO coalesce test to
allow running on top of a veth pair, so that no H/W dep
is required to run them.

By default gro.sh will use the veth backend, and will try
to use exiting H/W in loopback mode if a specific device
name is provided with the '-i' command line option.

No functional change is intended for the loopback-based
tests, just move all the relevant initialization/cleanup
code into the related script.

Introduces a new initialization helper script for the
veth backend, and plugs the correct helper script according
to the provided command line.

Additionally, enable veth-based tests by default.

v1 -> v2:
- drop unused code in setup_veth_ns() - Willem

selftests/net: GRO coalesce test

Implement a GRO testsuite that expects Linux kernel GRO behavior.
All tests pass with the kernel software GRO stack. Run against a device
with hardware GRO to verify that it matches the software stack.

gro.c generates packets and sends them out through a packet socket. The
receiver in gro.c (run separately) receives the packets on a packet
socket, filters them by destination ports using BPF and checks the
packet geometry to see whether GRO was applied.

gro.sh provides a wrapper to run the gro.c in NIC loopback mode.
It is not included in continuous testing because it modifies network
configuration around a physical NIC: gro.sh sets the NIC in loopback
mode, creates macvlan devices on the physical device in separate
namespaces, and sends traffic generated by gro.c between the two
namespaces to observe coalescing behavior.

GRO coalescing is time sensitive.
Some tests may prove flaky on some hardware.

Note that this test suite tests for software GRO unless hardware GRO is
enabled (ethtool -K $DEV rx-gro-hw on).

To test, run ./gro.sh.
The wrapper will output success or failed test names, and generate
log.txt and stderr.

Sample log.txt result:
...
pure data packet of same size: Test succeeded

large data packets followed by a smaller one: Test succeeded

small data packets followed by a larger one: Test succeeded
...

Sample stderr result:
...
carrier ready
running test ipv4 data
Expected {200 }, Total 1 packets
Received {200 }, Total 1 packets.
