[PATCH net] selftest/net: skip srv6_end_d[t/x][4/6]_*_test.sh if iproute2 too old

[PATCH net] selftest/net: skip srv6_end_d[t/x][4/6]_*_test.sh if iproute2 too old

[Alessio Faina]

In case iproute2 is older than version 5.14.0, released ~Sept 1, 2021,
the End.DT4/DT6/DX4/DX6 support are not available and the tests
contained in the following 4 test files
 - srv6_end_dt4_l3vpn_test.sh
 - srv6_end_dt6_l3vpn_test.sh
 - srv6_end_dx4_netfilter_test.sh
 - srv6_end_dx6_netfilter_test.sh
are failing in some kernel backports.
This is the result of one those tests in an unsupported environment:

\################################################################################
\TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant
\################################################################################
\
\    TEST: Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100)       [FAIL]
\
\    TEST: Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100)       [FAIL]
\
\    TEST: Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200)       [FAIL]
\
\    TEST: Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200)       [FAIL]
\

To amend this, check the current running iproute2 supports the required
feature and, if not, just skip the entire test to avoid a failure.

This is similar to what have been done for srv6_end_dt46_l3vpn_test.sh in

Oh, I just noticed this patch is better for net‑next.

Please wait for Jakub's reply. If not, You need to re-post it once net-next
opens again (Aug 31th).

Which kernel were you running when you saw these failures?

Did the ip route add commands that install the seg6local routes fail
there, and if so, with which error?
