dnsmasq-dhcp[1503]: DHCP packet received on eth0.102 which has no address

Fri Jan 29 13:01:26 EST 2021

Hello all!!

Just observing something strange happening on my router.
I am running openwrt 19.07.5 with updated dnsmasq package, opkg says
dnsmasq - 2.80-16.3

I had to isolate one lan port to use it like a WAN one with PPPoE.
My network config is:

config interface 'loopback'
 	option ifname 'lo'
 	option proto 'static'
 	option ipaddr '127.0.0.1'
 	option netmask '255.0.0.0'

config globals 'globals'
 	option ula_prefix 'fdb0:8649:f177::/48'

config interface 'lan'
 	option type 'bridge'
 	option ifname 'eth0.101'
 	option proto 'static'
 	option ipaddr 'xxx.xxx.xxx.xxx'
 	option netmask '255.255.255.0'
 	option ip6assign '60'

config switch
 	option name 'switch0'
 	option reset '1'
 	option enable_vlan '1'

config switch_vlan
 	option device 'switch0'
 	option vlan '101'
 	option ports '0t 1'

config switch_vlan
 	option device	switch0
 	option vlan	102
 	option ports	'0t 4'

config interface 'wan'
 	option ifname 'eth0.102'
 	option proto 'pppoe'
 	option username 'username'
 	option password 'pass'
 	list dns '208.67.220.220'
 	list dns '208.67.222.222'
 	list dns '208.67.222.220'
 	list dns '208.67.220.222'
 	option auto	1

The system seems to work well, except for the fact my logs are flooded by the message I posted in the subject:
