Update - Tried a different dongle - a 2.5Gbe and have two hard drives attached to the system. Doesn't matter where the 2.5Gbe dongle is attached, it eventually errors with "WARN Set TR Deq Ptr cmd failed" And the error rate is only around six times a day right now:

Since this drops the device from the system and offlines the link, I created a simple script to detect zero UP ethernet devices via cron once a minute and runs a ifnet -a. It's clunky but works.

crontab:
# m h dom mon dow command
* * * * * /root/fixnet.sh >/dev/null 2>&1

fixnet.sh:
#!/bin/sh

STATE=`ip link | grep " enx" | grep UP | wc -l`
if [ $STATE -gt 0 ]; then
  # All good. Exit
  exit 0
fi

/usr/sbin/ifup -a
sleep 20

ping -c 1 10.0.0.1 | grep "1 received"
if [ $? -eq 0 ]; then
  # Network looks good. Exit.
  exit 0
fi

sleep 310
ping -c 1 10.0.0.1 | grep "1 received"
if [ $? -ne 0 ]; then
  # The network is still down.
  systemctl reboot
fi
