In case iproute2 is older than version 5.11.0, released ~Feb 23, 2021,
the vrftable support is not available and the tests
contained in the following 2 test files
 - srv6_end_dt4_l3vpn_test.sh
 - srv6_end_dt6_l3vpn_test.sh
are failing in some kernel backports.
This is the result of one of 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]

The test installs a route with the vrftable feature; if this feature is
not available, the approach taken is to skip the test rather than
failing it.
