I agree, this knob should get a generic name and live in a generic
net/ directory to control this globally, so things don't break during
forwarding etc.
It does not solve the problem completely, e.g. when VMs send gso
packets through a vhost-net onto IPoIB, no?
Thanks,

I have understood more of the problem Hannes raises and I realize that
we need a slowpath in IPoIB to handle the problem
in question. I will make a new version of this patch with a more correct
position/name of the sysctl-variable.
I'll also make a separate patch adding the slowpath i IPoIB.
