a69c8a6183 net/icmpv6:Optimize the process of obtaining the IPv6 address through RA.
- When receiving Router Advertisement Message, if Managed Address
  Configuration flag is set, we should ignore the Autonomous
  Address-configuration flag, and obtain the IPv6 address via the
  stateful process.

cb161940c2 udp: Add support for SO_TIMESTAMP
Adds support for timestamping received UDP packets, either in
hardware or in kernel. Builds on the existing support of SO_TIMESTAMP
for SocketCAN.

Implementation uses CLOCK_REALTIME for timestamping to match the
behavior of Linux. This could be made configurable in future if needed.

4c99ad1ba9 net/utils: Switch argument order of net_ipv6_pref2mask
When implementing IPv6-related logic, we found the `net_ipv6_pref2mask`
and `net_ipv6addr_copy` are using different argument order:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(preflen, ifaddr->mask);
```
Change the order to:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(ifaddr->mask, preflen);
```

3e4d847f42 net/netdev: Support managing multiple IPv6 addresses by ioctl
1. Supporting `SIOCSIFADDR` and `SIOCDIFADDR` with Linux in6_ifreq struct to manage ipv6 addresses.
   Ref: https://man7.org/linux/man-pages/man7/netdevice.7.html
2. Supporting alias like 'eth0:0' for multiple IPv6 addresses, to keep previous ioctl `SIOCGLIFADDR`, `SIOCSLIFADDR`, `SIOCGLIFNETMASK` and `SIOCSLIFNETMASK` working.

bedcc5fc04 Add CONFIG_NET_ICMPv6_ROUTER_LIFETIME
Allows setting the advertised route lifetime, and also to set
it to 0 for advertising only the prefix.

From RFC4861:

   A router might want to send Router Advertisements without advertising
   itself as a default router.  For instance, a router might advertise
   prefixes for stateless address autoconfiguration while not wishing to
   forward packets.  Such a router sets the Router Lifetime field in
   outgoing advertisements to zero.

33c3abb706 net/tcp: Stop monitor in tcp_free
We may just free some TCP connections before monitor stopped, e.g.
sacrificie a TCP conn in `tcp_alloc` will just call `tcp_free` and reuse
the connection.  But we noticed that the TCP monitor is not released in
`tcp_free` because it is mounted on `conn->connevents` instead of
`conn->sconn.list` while `tcp_free` only release the latter.

7c422381ca net/tcp: Set SO_ERROR for poll error in setup
Normally, `SO_ERROR` for disconn events will be set by `tcp_poll_eventhandler`, but when the socket is closed before poll, we should also set the `SO_ERROR`.

On Linux, `tcp_poll` returns `EPOLLERR` event when `sk->sk_err` has value but doesn't let `poll` fail (doesn't set `errno`). https://github.com/torvalds/linux/blob/v6.5/net/ipv4/tcp.c#L594-L596
Note: `sk->sk_err` can be get by socket option `SO_ERROR` on Linux, so `POLLERR` will always be together with `SO_ERROR`.

Common libs like curl may try to read `SO_ERROR` on `POLLERR`.

   and prepare to wait sendsem;
2. interrupt by rptun thread, rpmsg_socket_ept_cb() is called to
   update conn->sendsize and post the sendsem, but the no one wait
   rx sem yet, so not post (see rpmsg_socket_post());
3. return to rpmsg_socket_connect_internal() to wait the sendsem, but
