Some more information, somewhat related to this bug. I bought a NUC 8i5
with an Intel onboard Ethernet. Installed Ubuntu Server 19.04 on it, and
quickly had poor networking speed: ping would rise to 600ms on the LAN
(like, on the same switch as my computer) as soon as I tried to install
something through apt. Resetting the interface would fix the ping on the
LAN for SSH sessions, but as soon as a download would restart, the ping
would rise again.
I downloaded the latest 3.4.2.1 driver from Intel (vs. the 3.2.6 driver
included in Ubuntu Kernel), built it (commenting get_settings and
set_settings, since it seems to have been removed) and it seems to have
fixed the issue (consistent 0.4-1.1ms ping on LAN, no troubles
downloading at full speed vs. being capped at 100KB/s in best-case
scenario).
