The main content of this submission is to limit both the TX/RX buffers
of TCP/UDP to throttled IOBs, avoiding impacts on the sending and
receiving of control-type messages.

Add CONFIG_NET_NO_LTO to allow compiling the network stack with -fno-lto.
This is useful for avoiding LTO-related issues in the network layer.

When an unrecognized ICMP (type=3, code=2) packet is received, the ICMP flow does not set dev->d_len to 0, causing a devif_loopback dead loop.
Therefore, in ICMP input processing, when an ICMP_DEST_UNREACHABLE message is received, if it is not ICMP_FRAG_NEEDED code, jump to typeerr for error handling.

Update the can_sendmsg() signature from "struct msghdr *msg" to
"const struct msghdr *msg" to match the updated sendmsg() prototype
and resolve compilation errors due to parameter type inconsistency.

To ensure consistency, in all places where the "sendmsg" function is used
either directly or indirectly, the type of the "struct msghdr *msg" parameter
needs to be modified to "const struct msghdr *msg".

This patch adds validation for IPv4 option lengths during packet processing
to prevent malformed packets from causing undefined behavior. The new
ipv4_check_opt() function verifies that option lengths are within valid
bounds before processing them.

This patch fixes the validation order in netdev ioctl handlers for
Bluetooth, IEEE 802.15.4, and packet radio devices. The command type
should be validated before checking the argument pointer to return
the correct error code (-ENOTTY vs -EINVAL).

During the autoconfig process, if the user modifies the link local
address while waiting for the Router Advertisement message, a crash will
occur when sending the ICMPv6 Neighbor Advertisement message because
netdev_ipv6_lladdr returns NULL.

The can_datahandler() function calls iob_tryadd_queue() to enqueue
received CAN data. Since iob_tryadd_queue() may return a negative
value on failure, the error was previously not properly handled.
Update can_datahandler() to propagate the return value so callers
can detect and handle queueing failures correctly.

dup2 and setsockopt can use the lock in conn to protect resources,
the lock in accept is originally used to protect the connection status.
however, only the send, recv, netpoll, and connect processes will
check this flag. only when the interface returns will the corresponding
conn structure be exposed to the caller, and then the above operations
can be performed. Therefore, this net_lock is not necessary.

arp_out will replace the dev->d_iob to arp request if the iob destination
address is not exist in arp table, this mechanism cause this iob lost
result in first received ping no response or first synack retransmit.
to fix this bug, we queue the iob if arp_out failed, allocate a new
iob to send arp request, after the arp request completed, then we retry
send the queue iob packet.
