The Intel igc Ethernet driver does not provide any statistical info in /proc/net/dev:
$ cat /proc/net/dev
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
enp6s0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
But this interface is used by many tools for showing network utilization. Nevertheless some statistical counters are available via ethtool:
$ ethtool -S enp6s0

I can confirm this bug.
Is commit 6b7ed22ae4c9 ("igc: Fix returning wrong statistics") fixing this issue?
In Debian, affected user confirmed the fix in https://bugs.debian.org/970722 .
Patch arrived in Fedora and seems to work. Many thanks!
