there is no need to call arp_out again to perform layer 2 header filling
in the arp_send process, so we should directly call the driver's callback.

otherwise, if the mld timers are not cancelled, an illegal address will
be accessed after timeout. to avoid this scenario, when the network card
is unregistered, all MLD timers must be attempted to be synchronously
cancelled.

insufficient IOB during IP fragment is a normal scenario and should
not crash directly. The assert needs to be removed and corresponding
error handling needs to be added.

When SOL_SOCKET options (e.g., SO_BINDTODEVICE via ping -I) hit ICMP sockets, icmp_{get,set}sockopt logged “Unrecognized ICMP option: 17” before fallback. Handle SOL_SOCKET explicitly by returning -ENOPROTOOPT so psock_* routes to the socket-level handler. Removes noisy logs without changing behavior (invalid devices still return -ENODEV).

This interface allows different protocol modules to use their own unique IOB
buffer sources and allocation strategies without interfering with each other.
Representative examples are the IP protocol and the CAN protocol. The IP
protocol generally transmits packets of varying lengths and requires
relatively high peak throughput. In this case, to ensure higher performance,
IOB_BUFSIZE is often configured to be relatively large, such as greater than
500. The CAN protocol generally transmits short packets of fixed length.
In this case, to improve memory utilization, IOB_BUFSIZE is often configured
to be relatively small, such as 16 or 64. To optimize the memory utilization
when the IP protocol and the CAN protocol share the same core,
this interface was added.

If the wdog use the fine-grained spin-lock, and allow the callback execution without the lock held, there will be incorrect interleaving.
E.g. The first `nxsem_timeout` callback function caused the second semaphore wait to fail.
Core 0 [nxsem_clockwait] | Core 1
enter_critical_section() | ...
wd_start(nxsem_timeout) | ...
nxsem_wait(sem) | wd_expiration() --> nxsem_timeout
wd_cancel(&rtcb->waitdog) | try enter_critical_section()
leave_critical_section() | Failed retry...
....nxsem_clockwait | Failed retry...
enter_critical_section() | Failed retry...
wd_start(nxsem_timeout) | Failed retry...
nxsem_wait(sem) | Core 1 enter the critical section
| nxsem_wait_irq(wtcb, ETIMEDOUT) -> incorrectly wake-up the rtcb.

The value returned by sizeof(struct note_start_s) is larger
than the actual memory footprint of struct note_start_s.
This causes the length calculated in sched_note_start to be larger
than the actual memory size,which further leads to out-of-bounds reads in note_common.
