When a mobile phone is connected, dhcpcd is used. After arp is broadcast, announce is sent less than once

[anqiao-cell]

When the dhcpcd5.2.10 version is used, no ip address is assigned when I connect to the mobile phone. After the carrier lost occurs after the lease is transferred to the ip address, the wireshark is used to capture the packet and check the log. When the ip address is allocated normally, the carrier lost packet is sent twice, and when an exception occurs, only one announce packet is sent. It should be certain that two announce packets are sent, but only one is sent in the log. Please help me analyze why only one announce packet is sent. Thank you

dhcpcd-5.2.10 is pretty old and very much unsupported. Can you try something newer like dhcpcd-10.0.6 please?
