What were you trying to do that didn't work?

when testing kseltest rtnetlink.sh, test pass on iproute-6.2.0-6.el9_4.x86_64, fail on iproute-6.11.0-1.el9.x86_64.

and I checked the outputs of "ip -6 netconf show" have no change, but return value is "0"  iproute-6.2.0-6.el9_4. while it turned to be 2 on iproute-6.11.0-1.el9.x86_64

[root@vm-10-0-186-189 net]# uname -r
5.14.0-547.el9.x86_64

[root@vm-10-0-186-189 net]# rpm -qa | grep iproute
iproute-6.2.0-6.el9_4.x86_64
iproute-tc-6.2.0-6.el9_4.x86_64

[root@vm-10-0-186-189 net]# sh ./rtnetlink.sh -t kci_test_bridge

PASS: bridge setup

after update iproute version

[root@vm-10-0-186-189 net]# uname -r
5.14.0-547.el9.x86_64

[root@vm-10-0-186-189 net]# rpm -qa |grep iproute
iproute-6.11.0-1.el9.x86_64
iproute-tc-6.11.0-1.el9.x86_64

[root@vm-10-0-186-189 net]#sh ./rtnetlink.sh -t kci_test_bridge

FAIL: ip netconf show test-br0

FAIL: ip netconf show testbr-vlan1

FAIL: ip netconf show test-dummy0
