Title:
e1000e driver - uploading slowed to a crawl.
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a Thinkpad T520 and a W520, both with the same ethernet device,
Intel 82579LM.
Running under Windows, speedtest reports ~1Gb up & down, so the
hardware is good. Under Ubuntu 18.04, kernel 4.15.0-50, I get ~1Gb
down but only ~4Mb (!) up.
e1000e is version 3.2.6-K and e1000 is version 7.3.21-k8-NAPI.
Note that I also have a Thinkpad T530 with those same versions of
driver, and it gives me ~1Gb in both directions.
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
Turning off ASPM in BIOS and via the kernel parameter pcie_aspm=off
Note that I also have a Dell Optiplex 980 with an 82578DM running
CentOS wich had the same problem (4Mb up). Turning off ASPM in BIOS
corrected the issue there.
I also note that there is another issue with this driver that was never
resolved:

Finally, I tried to install the most recent version of this e1000 and e1000e,
but they do not compile under Ubuntu 18.04:
