HedongGao opened a new pull request, #17702:
URL: https://github.com/apache/nuttx/pull/17702
## Summary
When the interface turns off the arp learning capability, it should not
learn arp from the IP message even if the ARP_IPIN function is enabled.
## Impact
The ARP_IPIN function is invalid for the interface that turns off the arp
learning ability.
## Testing
1. Enable the CONFIG_ARP_IPIN compilation option and set up the SIM test
environment;
2. Set the interface NOARP attribute in SIM;
3. Construct an icmp request message on the host side and send it to the
SIM. It is observed that there is no response from the SIM side;
4. The SIM end enables the interface ARP learning capability and sends the
icmp request message from the host again. The host end can receive the icmp
reply message.
