I also have the same controller but I didn't see watchdog timeout issues here. Since re(4) periodically cleans up transmitted frames the only guess I have is MSI issue. Could you try disable MSI and let me know whether it makes any difference on your box? Just add the following line to /boot/loader.conf file and reboot to make change effect. hw.re.msi_disable="1"
