[ovs-discuss] Mega-flow generation

[Sara Gittlin]

Billy,
Can you please refer me to the code where we start the megaflow creation to
the kernel upon an upcall,  and where we send it to the kernel via the
netlink socket ?
what i want to do is - to generate megaflows, based on openflow tables,
not neccesararily upon an upcall, that is not reactive mode and to send to
the kernel.
Another question is,  who is responsible to  associate a specific  megaflow
to the appropriate table in the cache ?  is it the kernel module or
vswitchd ?
Thank you
-Sara
