[ovs-discuss] ovs-vswitchd.service crashes

In case I turn off hw-offload with
ovs-vsctl set Open_vSwitch. other-config: hw-offload = false
then "ovs-vswitchd" is without collision.

Is it possible to reach someone who knows what to do with the offload problem?

Thank you for your help.

The problem is the same even if hw-offload is off.

I'm sending a log from ovs-vswitchd.log just after restarting the whole
openvswitch-switch.
Here you can see what happens before the assertion pops up.

ethtool -K phys1-1 hw-tc-offload off
ethtool -K phys1-2 hw-tc-offload off



This demonstrates turning off hardware offload at the ethtool level.
However, even with that, I believe that OVS will still try to use it if
OVS is configured for hardware offload.  It looks like your OVS does
have hardware offload enabled.  To turn it off, run:

ovs-vsctl set Open_vSwitch . other-config:hw-offload=false

Then restart OVS and see if it makes a difference.
