What's interesting is on a Dell Optiplex 3080 with a Realtek 8169 adapter I have similar symptoms (extremely slow downloads in the KB/s, and frequent packet drops seen in captures).

I'm seeing this also on Dell Precision 3650's with Intel I219-LM (rev 11) adapters, which lines up with some of the earlier posts in this thread.

The workaround above to disable auto power control resolves these symptoms on BOTH the Realtek 8169 and the Intel I219-LM adapters.

Oddly enough, a Dell Precision 3630 with a slightly different variant of the Intel I219-LM (rev10) does not have the same issues.

Not sure if any of this helps, but I was surprised to see it's not just Intel cards with these linux power control speed and packet loss symptoms...
