Hi Yuan-Chen
I tried:
"echo on | sudo tee /sys/bus/pci/devices/0000\:00\:16.0/power/control"
I also tried unloading mei* kernel modules.
However it didn't solve the isssue.
Here is the requested info:
# lspci -vvnns 00:1f.6

I also compiled the latest version of e1000e in
https://sourceforge.net/projects/e1000/
root@latitude-5420:~# modinfo e1000e | grep ver

srcversion: 035BD57B8D93A45D1668FCC
vermagic: 5.10.0-1038-oem SMP mod_unload modversions
But it didn't help.
I am currently using the wireless adapter until a find a solution.
Sadly, the only solution provided by technical support was to re-install
Ubuntu, which I will do when I find free time.
Many thanks,
Sebastian

Title:
e1000e extremly slow

Status in linux-oem-5.10 package in Ubuntu:
Confirmed
Bug description:
We have dell latitude 5420 & 5520 laptops with onboard intel ethernet
controller.
Problem is that the ethernet port is extremely slow. about 100kbyte/s
download throughput while on a gigabit connection. Upload seems to work just
fine.
Also when I pxe boot the system it's also painfully slow.
But here comes the funny part. When I attach a usb memory stick the
throughput of the networkcontroller is as expected.
I've used latest ubuntu 20.04.2 kernel 5.8.0-55
I've used latest ubuntu 20.04.2 kernel 5.10.0-1029-oem
Turns out this problem is not showing up when I manually install the
5.8.18 kernel.
Also when I create my own iso with the help of Cubic and install the
5.8.18 kernel in it the pxe boot is working as expected with high
throughput
system: Dell latitude 5420 + 5520
nic: Ethernet Connection (13) I219-LM
ubuntu 20.04.2
module: e1000e
Please assist. Thank you
