主题: Add more dhcp log about finding dhcp-config failed
Hi !
When dnsmasq attempts to search for the configured DHCPv6 address based on the
MAC address, it will send NS packets to obtain the client MAC address. If
dnsmasq fails to obtain the MAC address because any net reason, it cannot find
the configured DHCPv6 address. As a result, the client cannot obtain the MAC
address as expected. Adding some dhcp logs about finding dhcp-config failure
will help users to find the cause more quickly.
