Driver has suspect GRO implementation, TCP performance may be compromised.

Dear Linux folks,


Occasionally, Linux outputs the message below on the workstation Dell
OptiPlex 5040 MT.

    TCP: net00: Driver has suspect GRO implementation, TCP performance may be compromised.

Linux 4.14.55 and Linux 5.2-rc2 show the message, and the WWW also
gives some hits [1][2].

$ sudo ethtool -i net00
driver: e1000e
version: 3.2.6-k
firmware-version: 0.8-4
expansion-rom-version: 
bus-info: 0000:00:1f.6
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

Can the driver e1000e be improved?

Any idea, what triggers this, as I do not see it every boot? Download
of big files?


Kind regards,

Paul
