odroid H4+ with net card v2 (i226-v) network traffic stops with traffic

[0n3man]

I have an odroid H4+ with the net card v2 giving a total of 6 intel i226-v interfaces.  This is a clean install as I was looking to replace my current FW.  I initially had issues with the hard drive, which I got past. I then noticed the WAN interface seemed to be dropping out every couple of days.  I found the post that provided steps to update the nic firmware.  So I'm running the latest version of the intel nic firmware (FXVL_125C_V_2MB_2.32.bin).  This did not fix the issue.  I found a post where it was recommended to disable Energy-Efficient-Ethernet by setting the sysctl value for each nic to 1.  Turns out 1 is the default value after the install.  There was another post that indicated fc (flow-control) on the NIC could be a problem.  The default value here was 3, which means flow control is on.  I set it to 0 for each NIC.  Still no help.  I also turned off ASPM with sysctrl and also via the bios.

Once I noticed the WAN interface was dropping I decided to see how things faired while streaming video.  This causes the communications to drop out usually under an hour.  It's strange how things happen.  First normal traffic like DNS will stop being sent out over the WAN port.  However the video will keep streaming for a while. Anyway I'm looking for any other suggestions on how I might fix this.  I'm considering loading some form of VM host as I did that initially when I put my previous hardware in place.  Any thoughts on how to get pass this issue are appreciated.
