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
