Hi Lorenzo,

I don't think there is a need for default flow. If I understand
correctly, we are trying to handle
the scenario when the kernel generates the icmp needs frag error
packet. For the normal case i.e icmp
needs a frag error packet not generated by the kernel, it should
continue the normal flow.

I think with this we will end up adding two logical flows for every
logical port in the logical switch.
I don't think that's necessary.
I think we should add the logical flow only for logical switch ports
of type router.
The function should return immediately if !lsp_is_router(op->nbsp).
I think you can also match on the "inport == <lrp" in the first
logical flow of this function.
Also I don't think there is a need for the default flow below.
The below logical flow by-passes the port security check which could
be exploited by a rogue pod/VM.
Let me know if my suggestions don't work.
Thanks
