I installed FreeBSD 12.2 on an APU4D4 (bios 4.12.0.1) and configured a PF firewall with NAT on it and some other services (dhcp, bind).
The problem I'm having is that when I put it into service at the network edge, I can't get video-conferencing apps (google meet) to work with it, of all things (no video, sometimes no sound). Everything else seems to work fine.
The problems persist if I make the firewall totally open as well, so it doesn't appear to be caused by firewall rules.
I'm starting to suspect I haven't configured the drivers in the best way. Perhaps I'm not using enough queues, or using the wrong type of interrupts? I'm even starting to wonder if downgrading to FreeBSD 11 might help (I hear they overhauled the drivers for these devices between v11 and v12)
I know it's a bit of a shot in the dark, but here's the snippet from dmesg, when it probes the ethernet devices. Does anyone see any clues in there that might suggest a solution?
