 I have found why it can not work.
The root cause is buildroot . My compiler is build from buildroot.
And suppose if your turn on buysbox ipv6 (BR_IPV6) feature. It should be related to turn on uClibc option with ipv6 support on. but in my buildroot.
there is no related option. So even I turn on ipv6 on busybox, but the uClibc is still no ipv6 enable. So the problem happen. I need to manually turn on
uClibc ipv6 support . the everything fine.

Thanks for answer.
