The systemd-networkd just ignore the renew request. ``` 2024/09/14 21:46:00 no DHCP packet received within 10s 2024/09/14 21:46:00 retrying in 31.529038 seconds 2024/09/14 21:46:42 no DHCP packet received within 10s 2024/09/14 21:46:42 retrying in 63.150490 seconds 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: no more tries 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: renewal time expired, rebinding 2024/09/14 21:47:45 Link "eth1" down.
