[Sugesh] Hope its only the case of current implementation. Its possible to
change the hardware offload status at run-time in the future. The system will
re-populate the hardware ports accordingly when the status get changed.
We actually already changed that and the current implementation is same
as for dpdk-init where we can change from false to true during run time
but not from true back to false again. can be fixed later.
In case you do change this at run time we are missing to go over the
netdevs and add the needed ingress qdisc so this will be needed to be
done manually if working with this patchset.
We intend to fix this for V4.
I see the comment requiring restart also still exists for dpdk-init.
Maybe we should keep it currently as well until it's fully supported..
