Hi Sean,

It is a Netgate RCC-VE-8860 running as my home firewall.
https://netgate.com/docs/rcc-ve-8860/quick-start-guide.html

I am running FreeBSD 12-current r315466, using pf, dnsmasq, powerd,
hostapd, openntpd, nfs_client, vnstat, salt_minion, ng_netflow, and ppp as
a pppoe client.
The latter 2 are only running on the WAN interface igb1.
I have igb0, igb2, igb3, igb4 and wlan0 bridged together, with a static ip
as my LAN gateway assigned to bridge0.

I am seeing the error on igb3, which is the interface connected to my
desktop PC (dual booted Windows and FreeBSD).
