[ovs-dev] Need pointers in understanding Mac learning ovs bridge code flow(legacy)

[ravulakollu.kumar at wipro.com]

Hi All,

I am analyzing code for openvswitch with kernel datapath. For a mac learning switch implementation, I wanted to
Understand the code flow when a packet is arrived on vport(netdev). I could see upcalls to userspace when the packet
received on vport(netdev). Upcall handler doing DPIF_OP_FLOW_PUT (adding new flow entry)  & DPIF_OP_EXECUTE .
Can anyone please let me know in code where exactly userspace is consulting FDB to make the forwarding decision.

Thanks in Advance,
Uday
