The cleanup_v6() will cause the arp_ndisc_evict_nocarrier script exit
with 255 (No such file or directory), even the tests are good:
# selftests: net: arp_ndisc_evict_nocarrier.sh
# run arp_evict_nocarrier=1 test
# RTNETLINK answers: File exists
# ok
# run arp_evict_nocarrier=0 test
# RTNETLINK answers: File exists
# ok
# run all.arp_evict_nocarrier=0 test
# RTNETLINK answers: File exists
# ok
# run ndisc_evict_nocarrier=1 test
# ok
# run ndisc_evict_nocarrier=0 test
# ok
# run all.ndisc_evict_nocarrier=0 test
# ok
not ok 1 selftests: net: arp_ndisc_evict_nocarrier.sh # exit=255
This is because it's trying to modify the parameter for ipv4 instead.
Also, tests for ipv6 (run_ndisc_evict_nocarrier_enabled() and
run_ndisc_evict_nocarrier_disabled() are working on veth1, reflect
this fact in cleanup_v6().
