Public bug reported:
Hello! My problem is that I can’t seem to disable offloading of various
network operations (checksumming in particular) on my network adapter:
$ sudo ethtool -K eth0 rx off
Cannot set device rx csum settings: Operation not supported
According to hwinfo, my adapter uses the atl1e driver:
72: None 00.0: 10701 Ethernet
[Created at net.124]
Unique ID: usDW.ndpeucax6V1
Parent ID: rBUF.1owu3FJlCU9
SysFS ID: /class/net/eth0
SysFS Device Link: /devices/pci0000:00/0000:00:1c.5/0000:02:00.0
Hardware Class: network interface
Model: "Ethernet network interface"
Driver: "ATL1E"
Driver Modules: "atl1e"
Device File: eth0
HW Address: 00:22:15:95:14:b8
Link detected: yes
Config Status: cfg=new, avail=yes, need=no, active=unknown
Attached to: #32 (Ethernet controller)
I’m not quite familiar enough with kernel development to figure out the
exact situation, but I notice a patch exists that claims to enable this
feature; the commit ac936929092dc6a5409b627c4c67305ab9b626b3 should
enable one to find it. I can’t tell if this is applied and doesn’t work
or if it’s not part of our kernels.
