Bug Description
I have a Thinkpad T520 and a W520, both with the same ethernet device, Intel 82579LM.
When the T520 is running under Windows, speedtest reports ~0.93Gb down & ~1.05Gb up, so the hardware is good. Under Ubuntu 18.04, kernel 4.15.0-50, I get ~0.7Gb down but only a very reporoducible 4.15Mb (!) up. The W520 responds the same.
e1000e is version 3.2.6-K and e1000 is version 7.3.21-k8-NAPI.
Note that I also have a Thinkpad T530 which has the same Intel 82579LM and is running the same e1000 and e1000e driver versions, but under Ubuntu 16.04 (kernel 4.4.0-146). That is giving me ~.7Gb down and ~0.35Gb up. Better, but still definitely 1/3 of link capacity.
I have tried a number of attempted solutions which have had no effect:
ethtool -K eth0 gso off gro off tso off
ethtool -K eth0 tx off rx off
ethtool -G eth0 tx 256 rx 256
ethtool -G eth0 tx 8096 rx 8096
ethtool --set-eee eth0 eee off; ethtool --set-eee eth0 advertise 0
Turning off ASPM in BIOS and via the kernel parameter pcie_aspm=off
Note also that I also have a Dell Optiplex 980 with an 82578DM running CentOS which had a similar problem (4.8Mb up). Turning off ASPM in BIOS partially corrected the issue there. I now have speeds very similar to the Thinkpad T530 (~0.7Gb down, ~0.35Gb up)
I also note that there is another issue with this driver that was never resolved: https:/
Finally, I tried to install the most recent version of the e1000 and e1000e drivers, but they do not compile under Ubuntu 18.04 and I am now told this is no longer supported: https:/
