## Summary
If Managed Address Congfiguration flag in the Router Advertisement Messsage
is set, we would obtain the IPv6 address though the stateful DHCPv6 procedure.
## Impact
The change will affect the process of obtaining IPv6 address by `renew6`.
## Testing
We can use radvd to simulte the IPv6 server, and control the RA flags by
turning on or off the `AdvManagedFlag` field.
- open the `NET_ICMPv6_AUTOCONF`;
- then, get the IPv6 address by `renew6`;
- and check the result with `ifconfig`;
The radvd configuration is as follows:
```
interface nuttx0 {
IgnoreIfMissing on;
AdvSendAdvert on;
MinRtrAdvInterval 200;
MaxRtrAdvInterval 600;
AdvOtherConfigFlag on;
AdvManagedFlag on;
AdvLinkMTU 1500;
prefix 2408:501:ffff:abc::/64 {
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
AdvValidLifetime 600;
AdvPreferredLifetime 600;
};
route 2408:501:ffff:f01::/64 {
};
};
```
