Network unusable (>1s-5s pings) on e1000e

[Diego Remolina]

On DELL 7060 MicroFormFactor (MFF) machines with Intel network cards, installing any kernels above, but not including 4.15.0-20, break the network connectivity of the machine.

Latest kernel where network card works:
linux-image-4.15.0-20-generic 4.15.0-20.21~16.04.1 amd64 Signed kernel image generic

Tested kernels where network card breaks:
4.15.0-22
4.15.0-33
4.15.0-36

# lspci -nn -d ::0200
00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:15bb] (rev 10)

BIOS Information
        Vendor: Dell Inc.
        Version: 1.2.14
        Release Date: 09/06/2018

To reproduce the issue:

1. Install any kernel starting on 4.15.0-22 or above
2. Boot the machine with the new kernel
3. ping the gateway (pings are in the sub 1ms range)
4. Attempt to do things that use the network, i.e. apt update or scp, etc. It may take a minute or so before things get hung, i.e. you will see apt update progress stop and the transfer rate drop down to just a few kb/s or simply say stalled.
4. Now ping the gateway again and you will see 1-5s pings, dropped packets
5. At this point network is no longer usable

After coming back from the weekend, the issue is now also occurring on the 4.15.0-20 kernel. I am not sure what is up. I had tried the 4.15.0-22 and 4.15.0-36 kernels, prior to booting up 4.15.0-20 again. In this particular machine, I had tried resetting the power saving settings of the network card from a Windows install, per bug that could be related: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1785171

To make this issue ever more confusing, we have another DELL 7060 running 4.15.0-36 where the network card is working perfectly and the issue has not come up at all.

From my latest test on 4.15.0-20 and some discussion with TJ- in IRC, he asked me for some output to look at sysfs output from the card. Here it is:
